What “energy footprint” means

When light energy enters the head through a single point, it doesn’t stay as a tiny dot. As it passes through skin, skull, the fluid around the brain (CSF), and cortex, multiple scattering events spread and redirect the beam. The resulting energy footprint is broad, overlapping fields of light fluence.

The Vielight Neuro 4’s geometry is engineered to intentionally overlap these broadened fields over Default Mode Network (DMN) nodes with the highest independently measured irradiance in commercially available brain photobiomodulation devices, while still bathing the wider cortex. This is why five VieLED modules can produce an effect that is effectively full‑transcranial, with a focus on the DMN.

Plain‑English summary: Five specialized LEDs ≠ five dots. Physics turns five dots into five large, overlapping halos that cover the cortex, with positioning that accentuates DMN hubs.

The Vielight Neuro Pro 2, with twelve higher-powered VieLED modules, produces an even stronger intensity with the ability to target more networks individually for precision-based photobiomodulation.

Why Five Vie-LEDs provide full Transcranial Coverage

A CMOS-based camera was used to detect and translate 810nm (invisible to the human eye) fluence through a human skull.


1) Skull scattering amplifies coverage.
The skull’s (bone) mineralized matrix is highly uneven. Incoming photons undergo Mie‑dominant scattering, so a narrow beam entering bone emerges as a wide-spread halo with a concentration on contact points.

2) Skin/scalp. The scalp consists of collagen fibers, fat, and small blood vessels—each of these components absorb, scatter and refract light energy.

3) Cerebrospinal fluid (CSF) scatters photons. The liquid which the brain floats in, cerebrospinal fluid (CSF) also scatters light energy, helping spread light energy sideways, so it fans out over the tops of the brain’s folds and into nearby areas.

4) Overlapping light halos → whole‑cortex coverage. The Vielight Neuro 4’s VieLEDs are strategically positioned so their broadened halos overlap across the brain. The result is full coverage but with a focus on the Default Mode Network (DMN).

DMN 1

Figure 1: The DMN in cerebral brain scans in different mental states.

DMN‑Focused Geometry (With full transcranial PBM)

A dysfunctional Default Mode Network is linked with psychiatric problems like Alzheimer’s, Parkinson’s, etc. In traumatic brain injuries (TBI), the DMN is often disrupted—its connections can become weaker or noisy, and the brain struggles to switch off the DMN and switch on task networks, which maps to brain-fog, slowed thinking, fatigue, and problems with attention and memory. Which is why improving functional connectivity of the DMN is so important in research.

For creativity, the DMN supplies the raw material—spontaneous associations, memory recombination, daydreaming—while the salience and executive networks pick, refine, and test those ideas; the healthiest pattern isn’t a constantly high DMN, but flexible switching between DMN and task networks, which predicts better divergent thinking and creative output.

The Vielight Neuro 4’s layout concentrates on these hubs so the diffuse halos focus where the DMN nodes reside, while still spreading energy into frontal, temporal, and lateral parietal cortices. This DMN‑weighted strategy aligns with the Neuro 4’s intent to support large‑scale network dynamics while maintaining whole‑brain coverage.

Bottom line: It may look like “just five super powerful LEDs,” but their collective energy footprint blankets the cortex and leans into the DMN where hubs are densest.


The Neuro Pro 2: Higher Intensity & Programmable Network Targeting

The Vielight Neuro Pro 2 extends the principles described above by combining 12 VieLED modules with higher‑intensity output with module‑level control to realize stronger full‑transcranial PBM with network‑specific emphasis.

  • Higher irradiance & total power: Twelve patented VieLEDs provide the highest surface irradiance in the industry, creating ample headroom for dense hair, thicker calvaria while preserving safety via app‑controlled duty cycles and session timing.
  • 12 programmable, flexible modules: Independently activate, sequence, and synchronize modules to target any cortical territory or all‑network coverage. Patterns can be designed to stack energy over selected large‑scale networks (e.g., DMN, dorsal attention, salience, frontoparietal, sensorimotor).
  • Personalized & automated neuromodulation: The Neuro Pro app supports guided presets as well as deep manual control (e.g., frequency selection, phase relationships, duty cycle, cross‑frequency coupling). These capabilities enable personalized protocols and can be orchestrated into automated, AI‑assisted workflows for network‑specific neuromodulation and repeatable routines.
  • Full‑brain continuity with intranasal channel: Superior to the Neuro 4, the Neuro Pro 2 integrates two intranasal pathways to leverage the porous, thin cribriform plate to reach ventral brain structures .

TL;DR: The Neuro Pro 2 keeps the full‑transcranial, network‑aware energy footprint concept and adds more power and programmable control so you can shape where, when, and how energy is delivered across brain networks.

The Intranasal Channel: Reaching Ventral Brain Structures

Transcranial delivery is complemented by an intranasal module. Here, the cribriform plate – the thinnest, porous portion of the skull, which connects the olfactory bulb with the olfactory nerves creates a naturally porous, short optical path to ventral frontal territories at the brain’s base, easily enabling light energy to pass through. This underside access helps address deep/ventral targets that are inaccessible transcranially.

Transcranial (tPBM) + Intranasal (iPBM) brain photobiomodulation = Intranasal-transcranial PBM (itPBM) and is unique to Vielight.

Pathway to the Olfactory Bulb and vmPFC

The olfactory bulbs sit just above the nasal cavity on the thin, perforated cribriform plate. Positioning the intranasal emitter near the nasal roof creates a short path to the bulbs and along the olfactory tracts.

Just behind and above this region lies the ventromedial/orbitofrontal prefrontal cortex on the underside of the frontal lobes, so the intranasal route offers a practical doorway toward ventral frontal areas.

In practice, it complements transcranial delivery—providing dorsal‑to‑ventral continuity with Neuro 4, and higher‑intensity, programmable timing with Neuro Pro 2.

Takeaway: The intranasal channel is not a side feature—it is a purpose‑built optical route through the porous, thin cribriform plate to reach the olfactory bulbs and ventral/medial prefrontal cortex, completing Neuro 4/Pro 2’s full‑brain energy footprint from the underside.


Seeing is Believing: CMOS Smartphone Photonic Detection

To make the diffusion concept visible, we ran simple visual experiments using a CMOS smartphone camera and a real human calvaria (see video below):

  1. Setup: The Vielight Neuro 4 and Vielight Neuro Pro 2 are positioned below a real human skull’s calvaria, which rests on top of it. A smartphone camera, sensitive enough to detect relative near‑infrared light despite typical IR filtering – captured trans‑bone light patterns.
  2. Observation: Each VieLED produces a vibrant, wide intensity field, not a narrow spot. Overlapping fields were evident as brighter, blended regions.
  3. Interpretation: The relative intensity maps match expectations from multiple scattering and interface redirection across bone, meningeal, and CSF boundaries.

What this is and isn’t: The smartphone method is a qualitative, relative visualization – useful for pattern‑tracking and comparative intensity across positions. It is not a calibrated dosimetry system and doesn’t replace formal optical modeling or in‑tissue fluence measurements.


A Quick Tour of the Physics (In Brief)

  • Scalp & skull: High reduced scattering and modest absorption broaden and attenuate incident beams, creating diffuse halos.
  • Dura/arachnoid/CSF: While CSF is comparatively low‑scattering, interfaces and surface irregularities (arachnoid, trabeculae, sulcal geometry) redirect and redistribute light, aiding lateral spread across adjacent gyri.
  • Gray matter: Additional forward‑biased scattering continues to smooth and widen the footprint within cortex.

Together, these layers transform point‑like sources into distributed fields that can be stacked where we want emphasis (e.g., DMN hubs) while maintaining broad coverage elsewhere.


Limitations & Next Steps

  • Qualitative visualization: CMOS camera capture provides relative intensity, influenced by sensor IR filtering and auto‑exposure. Future work can add spectral characterization and fixed‑exposure protocols.
  • Heterogeneity: Skull thickness, diploë content, sinus cavities, and CSF thickness vary across individuals, subtly reshaping footprints. Ongoing Monte Carlo modeling and in‑vivo NIRS/NIRI can refine priors.
  • Dosimetry bridge: Linking surface power, fluence rate at depth, and biologic response remains an active engineering task. Calibrated phantoms and paired imaging can tighten these relationships.

Conclusion

The Vielight Neuro VieLED architecture is deceptively simple: by leveraging tissue optics, it yields an effectively full‑transcranial energy footprint with a purposeful DMN bias. The intranasal channel completes the map by accessing ventral forebrain across the porous cribriform plate, creating a complementary dorsal‑to‑ventral pathway. The calvaria‑based visualizations make the physics tangible—five LEDs, one brain‑wide footprint, with DMN‑centered emphasis by design.

What is Vie-LED® Technology? The Importance of Irradiance https://www.vielight.com/blog/what-is-vie-led-technology-the-importance-of-irradiance/ Sat, 21 Jun 2025 00:42:36 +0000 https://www.vielight.com/?p=48952

At the heart of Vielight’s innovation lies a proprietary engineering breakthrough: Vie-LED® technology. Designed specifically for transcranial and intranasal photobiomodulation (PBM), Vie-LED is not just another light-emitting diode system. It’s a meticulously optimized delivery mechanism that enables high irradiance output with minimal heat generation, ensuring both therapeutic potency and user safety.


High Irradiance, Minimal Heat – A Rare Engineering Achievement

In photobiomodulation, irradiance (measured in milliwatts per square centimeter, mW/cm²) is one of the most critical parameters for therapeutic efficacy — especially when targeting the brain, where light must pass through multiple layers, including scalp, skull, and cerebrospinal fluid.

While many devices boast numerous LEDs, more does not mean better if the light energy does not penetrate the skull due to weak irradiance. Vie-LED® modules are engineered to emit targeted, high-power light intensities, reaching therapeutic thresholds needed for neurostimulation – typically 200–300 mW/cm², depending on the model.

Crucially, this is achieved without overheating, thanks to proprietary internal design features that include:

  • Efficient heat sinks

  • Precision current regulation

  • Tight spectral control at optimal therapeutic wavelengths (e.g., 810 nm for deep penetration)

This sets Vielight apart in a field where high power often comes at the cost of discomfort or safety risk.


Visual Proof: Near-Infrared Light Penetrating the Skull with Vielight Neuro 4

The Vielight Neuro has the deepest penetration in the brain photobiomodulation field. The demonstration video below with a real human skull and the Vielight Neuro clearly demonstrates 810nm light energy with an irradiance of 250 mW/cm2 clearly passing through the skull’s calvaria.

The Vielight Neuro features proprietary Vie-LED technology—highly specialized, custom-engineered LEDs designed to deliver optimal irradiance for brain stimulation without producing excess heat. To ensure safety and efficiency, we’ve intentionally limited the device’s power density to 50% of its maximum potential output. Even still, it features the highest irradiance in the field of brain photobiomodulation according to independent 3rd party tests.


What About Devices With More LEDs?

Helmet brands often highlight a higher number of diodes. However, these typically operate at much lower irradiance levels — sometimes as low as 6–15 mW/cm², according to independent lab tests (e.g., PBM Foundation 2024 irradiance comparison).

MegaLab and Optronic Lab, photonics engineering firms, conducted two mutually exclusive tests with correlative results:

  1. Read the full independent test report from Optronic Lab here.
  2. Read the full independent test report from MegaLab here.
  3. Megalab’s testing methodology.

But why does that matter?

In brain PBM, light attenuation is exponential, only a fraction reaches cortical neurons. Without sufficient irradiance at the surface, the actual dose delivered to the brain tissue is negligible, regardless of how many LEDs are used. Think of it like trying to light up a room using dozens of flashlights with dying batteries, brightness matters more than quantity.


Clinically Validated — Backed by Over 20 Published Clinical Studies

Vie-LED is not just an engineering concept; it’s the engine powering over 50 published or ongoing clinical studies, including:

  • Double-blind trials on cognitive function and dementia

  • Research into concussion recovery and mental health

  • Studies with military, university, and hospital collaborators globally

This robust body of research reflects the consistency and reliability of the Vie-LED output profile — something essential for replicable results in clinical settings.


Why Vie-LED Matters for You

When selecting a photobiomodulation device, scientific precision, power delivery, and safety should outweigh superficial features like LED count or flashy casing. Vie-LED delivers on what matters most:

Sufficient irradiance for therapeutic effect
Low heat for safety and comfort
Rigorous clinical validation
Designed specifically for the brain and intranasal regions

Whether you’re a clinician, athlete, or health-conscious individual, Vie-LED is a testament to purposeful engineering, not mass manufacturing.


Explore the science. Feel the difference. Trust the technology.
This is Vie-LED®. This is Vielight.

Are Neurons extra sensitive to light energy? https://www.vielight.com/blog/neurons-light-sensitivity-photobiomodulation-insights/ Fri, 30 May 2025 14:27:13 +0000 https://www.vielight.com/?p=48522

Are Neurons Extra Sensitive to Light Energy?

The idea that light can influence the brain isn’t science fiction, it’s science. In recent years, the field of photobiomodulation (PBM) has uncovered how light energy, particularly in the red and near-infrared spectrum, can interact with our cells in surprisingly therapeutic ways. But are neurons, our brain’s most vital and complex cells, especially sensitive to this kind of energy?

What is Photobiomodulation?

Photobiomodulation refers to the use of specific wavelengths of light to stimulate cellular function, most notably through mitochondrial mechanisms. The most common wavelengths used are in the red (600–700 nm) and near-infrared (760–1100 nm) range. These wavelengths penetrate biological tissues and are absorbed by intracellular photoreceptors, particularly cytochrome c oxidase (CCO) in mitochondria, leading to increased ATP production, modulation of reactive oxygen species, and changes in gene expression [1].

Why Neurons Might Be More Sensitive

Neurons are highly metabolically active and rely heavily on mitochondrial function. Since they are post-mitotic and do not easily regenerate, their health is tightly linked to mitochondrial performance. This may explain why they respond especially well to light stimulation.

  • High mitochondrial density: Neurons have a large number of mitochondria to support their energy needs, especially in synapses [2].
  • Vulnerability to oxidative stress: The brain uses about 20% of the body’s oxygen but comprises only ~2% of its mass. PBM’s ability to regulate redox balance offers potential neuroprotection [3].
  • Modulation of neuroinflammation: Light energy has been shown to reduce inflammatory markers and glial activity, both of which affect neuron health [4].

Supporting Evidence

1. Improved Cognitive Function

A randomized controlled trial found that near-infrared PBM applied to the prefrontal cortex improved attention and memory in healthy adults [5].

2. Neuroprotection After Injury

In rodent models of traumatic brain injury, PBM preserved neurons, reduced glial scarring, and stimulated regeneration [6].

3. Functional Imaging Studies

EEG and fMRI studies have shown increased brain activity and connectivity after PBM, suggesting direct effects on neural networks [7].

4. Applications in Neurodegenerative Disorders

Early human studies indicate benefits for Alzheimer’s and Parkinson’s patients, including improved mood, memory, and sleep [8].


Can Light Really Reach the Brain?

The human skull filters out much light, but near-infrared wavelengths, especially in the 810–1070 nm range, can penetrate to the cortex. Studies estimate that enough light reaches cortical tissue to stimulate a biological response, especially when higher-power or pulsed devices are used [9].

Visual Proof: Near-Infrared Light Penetrating the Skull with Vielight Neuro 4

The Vielight Neuro has the deepest penetration in the brain photobiomodulation field. The demonstration video below with a real human skull and the Vielight Neuro clearly demonstrates 810nm light energy with an irradiance of 250 mW/cm2 clearly passing through the skull’s calvaria.

The Vielight Neuro features proprietary Vie-LED technology—highly specialized, custom-engineered LEDs designed to deliver optimal irradiance for brain stimulation without producing excess heat. To ensure safety and efficiency, we’ve intentionally limited the device’s power density to 50% of its maximum potential output. Even still, it features the highest irradiance in the field of brain photobiomodulation according to independent 3rd party tests.

Conclusion

So, are neurons extra sensitive to light energy? Current research strongly suggests yes. Due to their high energy demands and mitochondrial density, neurons are well-positioned to benefit from photobiomodulation. Whether enhancing cognitive performance, protecting against injury, or slowing neurodegeneration, PBM appears to offer a non-invasive, promising method to support Brain wellness.

Vielight Vagus: Scientific Foundations and Applications of Vagus Nerve Stimulation https://www.vielight.com/blog/vielight-vagus-scientific-foundations-and-applications-of-vagus-nerve-stimulation/ Mon, 12 May 2025 19:08:51 +0000 https://www.vielight.com/?p=48073

Introduction

The vagus nerve plays a central role in autonomic regulation, inflammation control, mood modulation, and overall homeostasis. Vagus nerve stimulation (VNS) is a promising approach for enhancing autonomic balance, reducing systemic inflammation, improving mental health, and supporting neuroplasticity.

The Vielight Vagus presents an innovative, non-invasive alternative using photobiomodulation (PBM) to target the cervical vagus nerve branches with pulsed near-infrared light. Controlled clinical studies are being planned to evaluate its efficacy.

Disclaimer

The Vielight Vagus is marketed as a low-risk general wellness device without medical claims. This white paper provides biological and mechanistic context for its design.

Device Overview

  • Target: Bilateral cervical vagus nerve branches under the sternocleidomastoid (SCM) muscles
  • Delivery: Hands-free headset for consistent anatomical placement
  • Website: Vielight Vagus Device
  • Patent: Patent Information

Early Experimental Outcomes

Experiments using 810 nm PBM at 50 mW/cm² demonstrated a notable increase in vagal tone at 100 Hz pulse frequency, aligning with results from electrical VNS studies (Sclocco et al., 2020; Yokota et al., 2022).

Scientific Rationale and Mechanisms of Action

Foundational Mechanisms

PBM stimulates afferent vagal fibers via mitochondrial activation, calcium signaling, and ROS modulation [Hamblin, 2016; Karu, 1999].

Distinct from Electrical Stimulation

PBM does not rely on electrical depolarization but works through photoactivation of ion channels and metabolic support [Zhang et al., 2024; Yan et al., 2025; Farazi et al., 2024].

Potentially Shared Outcomes

  • NTS Activation: fMRI studies show cervical VNS activates the NTS, DMNV, and PAG [Yakunina et al., 2020; Benarroch, 2012]
  • HRV Modulation: Non-invasive VNS improves HRV, a marker for mental health resilience [Bretherton et al., 2022; Shaffer & Ginsberg, 2017]

Other Advantages of the Vielight Vagus

  • 100 Hz Pulsing: Aligned with gamma frequencies for cognitive support [Herrmann et al., 2010; Yokota et al., 2022]

Helpful PBM Mechanisms of Action

  • Mitochondrial upregulation via cytochrome c oxidase
  • Increased ATP and nitric oxide release
  • Modulation of calcium channels and ion transport
  • Systemic anti-inflammatory effects

Future VNS Applications for PBM Investigation

  • HRV and autonomic balance enhancement
  • Stress and anxiety support

Conclusion

The Vielight Vagus device introduces a next-generation approach to non-invasive VNS. By combining the benefits of photobiomodulation with cervical vagus nerve stimulation, it offers a safe, comfortable, and effective alternative to traditional VNS methods. Its design supports home-based clinical research and HRV enhancement with minimal user burden. Vielight’s upcoming investigations aim to validate and expand its potential therapeutic applications.

Introduction

Concussions, traumatic brain injuries (TBI), and neurodegenerative conditions present ongoing challenges in neurorehabilitation. During a recent lecture delivered by leading neuro-optometrists Dr. Charles Shidlofsky and Dr. DeAnn Fitzgerald, attendees were introduced to a novel adjunctive modality in neurorehabilitation: the Vielight Neuro, a non-invasive photobiomodulation (PBM) technology designed to deliver near-infrared (NIR) light to the brain.

Why Recovery Outcomes Differ: A Clinical Observation

Dr. Fitzgerald posed a critical question during her lecture: why do individuals with similar brain injuries often experience vastly different recovery outcomes? She pointed to neuroinflammation, mitochondrial dysfunction, and autonomic dysregulation as key variables. Without addressing these foundational issues, traditional rehabilitation efforts—such as vision therapy, vestibular rehabilitation, and cognitive retraining—may be less effective.

The Vielight Neuro: A Tool to Support Neuroplasticity

With her many years of clinical work with the Vielight Neuro, Dr. Fitzgerald proposes the Vielight Neuro as a tool to reach cortical regions and interact with mitochondria, due to its optimal irradiance and 810nm NIR wavelength.

Scientific and clinical observations presented in the lecture highlighted several PBM-supported processes:

  • ATP Production: Enhanced mitochondrial output for increased cellular energy.
  • Anti-inflammatory Action: Downregulation of neuroinflammation.
  • Neuroplasticity Support: Activation of brain-derived neurotrophic factors (BDNF) and synaptic remodeling.
  • Autonomic Regulation: Shifting from sympathetic dominance to parasympathetic balance, supported by vagus nerve stimulation.

Lecture Case Examples: Application in Clinical Settings

The presenters shared a number of anonymized case observations. In concussion management, application of the Vielight Neuro device prior to or during neuro-vision therapy sessions appeared to correlate with:

  • Reduced headache frequency and photophobia within weeks
  • Improvements in reaction time and cognitive performance
  • Enhanced readiness for traditional therapies like eye tracking and balance training

In one Parkinson’s case, 12 weeks of structured PBM exposure coincided with:

  • Improved contrast sensitivity
  • Enhanced gait and balance
  • Reduced cognitive fatigue

While causality cannot be confirmed, these observational insights supported further exploration.

Scientific Insights from Dr. Lew Lim

Dr. Lew Lim, founder of Vielight, expanded on the underlying science. He referenced functional MRI studies conducted at Baycrest Hospital (University of Toronto) with a new Vielight laser apparatus, in which intranasal and transcranial brain stimulation demonstrated measurable brain-wide responses:

  • At 150 mW/cm² transcranial, blood-oxygen-level-dependent (BOLD) imaging showed increases in cerebral blood flow and activation.
  • Optimal results were observed at 10 Hz (alpha) and 40 Hz (gamma) pulse frequencies.

These findings align with earlier data from studies with the Vielight Neuro at the University of Utah and Brigham Young University, which tracked improvements in balance, reaction time, and mood in athletes exposed to repetitive head impacts.

PBM via the Vielight Neuro is theorized to act through:

  • Nitric oxide release, enabling vasodilation and perfusion
  • ATP synthesis for cellular energy
  • Activation of transcription factors such as NF-kB and Nrf2
  • Support of mitochondrial efficiency and reduction of oxidative stress

Potential Applications Discussed

The speakers emphasized the need for further study but highlighted areas under active investigation, including:

  • Visual Snow Syndrome
  • Long COVID-related brain fog
  • Stroke-related visual field issues
  • Neurodegenerative conditions such as Parkinson’s and mild cognitive impairment

Device Use: In-Clinic and at Home

Due to the device’s sensitive construction, most use occurs in-clinic. However, practitioners noted that patients are increasingly purchasing the Vielight Neuro Duo for home use under clinical guidance. Additionally, the Vielight Vagus device—targeting the vagus nerve—was discussed for its role in supporting parasympathetic activity and sleep regulation.

Conclusion: A New Frontier in Brain Stimulation

This lecture reinforced that photobiomodulation via the Vielight Neuro is an emerging area of interest in neurorehabilitation. By potentially influencing key pathways related to energy production, inflammation, and brain network reorganization, the technology offers new avenues for enhancing resilience and recovery.

As the field advances through more rigorous research and clinical trials, including studies aiming for FDA clearance, the Vielight Neuro may continue to gain traction as a tool for supporting neurological function across a range of applications.

Irradiance is Power: The Key to Effective Brain Photobiomodulation https://www.vielight.com/blog/irradiance-the-key-to-effective-brain-photobiomodulation/ Wed, 15 Jan 2025 22:08:28 +0000 https://www.vielight.com/?p=44168

In brain photobiomodulation, near-infrared (NIR) light within the 810–1100 nm wavelength range offers beneficial cellular effects and deep tissue penetration. However, if the wavelength is optimal but the irradiance (surface power density) is too weak, penetration will be minimal or nonexistent.

The two most critical factors determining the efficacy of this therapy are irradiance (surface power density) and wavelength, which determine depth and cellular effects. This article explores the significance of these metrics and why brain PBM requires a higher irradiance than natural sunlight to achieve its unique benefits.

Understanding Irradiance in Photobiomodulation

Irradiance, measured in milliwatts per square centimeter (mW/cm²), refers to the concentration and intensity of light energy delivered to a specific area.

  • Irradiance is the concentration of light energy delivered to a specific area, and in brain photobiomodulation, it determines how effectively the light can stimulate brain cells and improve function.
  • Think of irradiance as the brightness of a light source —it needs to be strong enough to reach and activate your brain cells. If it’s too weak, the light won’t penetrate deeply or have any meaningful effect on your cells. Sunlight can be a useful benchmark.

For comparison, natural sunlight in the near-infrared (NIR) range is free and typically has an irradiance of 50-100 mW/cm² at the Earth’s surface. While sunlight exposure provides some level of photobiomodulation—notably through NIR light—its diffuse nature and accessibility already makes it a routine part of daily life for most people. To provide a meaningful therapeutic advantage, brain photobiomodulation devices must deliver higher irradiance levels than sunlight, ensuring benefits beyond what can be achieved through standard sunlight exposure.

2024 systematic review that screened 2,133 records and included 97 brain-PBM studies reports that irradiance (power density) was typically ~250 mW/cm². The Vielight Neuro slightly exceeds the irradiance used in these studies, which included lasers. Optimal irradiance ensures that enough light energy reaches the neurons, stimulating mitochondrial activity, increasing ATP production, and supporting neurogenesis and synaptic plasticity.

Figure - Near-invisible 810nm NIR energy capture of Vielight Neuro using photosensitive equipment, Department of Bioengineering, Uniformed Sciences University

Why Brain PBM Needs a Higher Irradiance than Sunlight

Brain PBM devices should be designed to deliver focused, high-irradiance light directly to the head within the NIR range and bypass hair, to ensure benefits beyond what can be achieved through standard sunlight exposure. The Vielight Neuro, which is supported by the most published brain photobiomodulation studies across a wide variety of fields has an irradiance exceeding 200 mW/cm² to ensure sufficient energy reaches neural tissues.

In published studies, higher irradiance levels enable targeted stimulation of mitochondrial activity, leading to enhanced cognitive function, improved mood, and potential therapeutic effects for conditions like Alzheimer’s disease, Parkinson’s Disease and traumatic brain injury. Higher irradiance levels also enable full transcranial coverage with fewer LEDs.

2024 systematic review that screened 2,133 records and included 97 brain-PBM studies reports that irradiance (power density) was typically ~250 mW/cm². This is because getting light energy through the skull, skin and cerebral spinal fluid requires a lot of energy and an appropriate wavelength to trigger beneficial neurophysiological effects.

Irradiance Measurement Case Study

As part of their testing program to standardize irradiance reporting, the PBM Foundation benchmarked the Vielight Neuro 3 against two PBM helmets — the Suyzeko NIR helmet and the Neuronic Neuradiant — in collaboration with two photonics engineering firms. Both MegaLab and Optronic Lab conducted independent tests, yielding strongly similar and replicable results

MegaLab and Optronic Lab, photonics engineering firms, conducted two mutually exclusive tests with strongly similar results:

  1. Read the full independent test report from Optronic Lab here.
  2. Read the full independent test report from MegaLab here.
  3. Megalab’s testing methodology.

Based on the 2024 systematic review of 97 brain-PBM studies, the Vielight Neuro (180-350 mW/cm2) is inline with the 250 mW/cm2  average, which included lasers. The Neuronic and Suzyeko helmets only generated less than 5% of the 250 mW/cm2  average.

Studies support a higher irradiance

Vielight technology is featured in the most published research in the field of brain photobiomodulation by a significant margin.

Be cautious of companies attributing research conducted with Vielight devices or other devices as attainable to their own.

Brain photobiomodulation is parameter-specific and our Vie-LED technology generates a unique laser-like profile and an industry-leading irradiance, which other devices cannot easily emulate.

The table below is a benchmark studies published comparison against other random PBM helmets.

A study by the University of Texas at Arlington investigated the effects of photobiomodulation (PBM) on the forearm using different light sources (800 nm laser, 1064 nm laser, and 810 nm LED) on vascular hemodynamic oxygenation (Δ[HbO]) and cytochrome c oxidase (CCO) redox metabolism (Δ[oxCCO]) in vivo. A key variable within their study: an irradiance greater than 100 mW/cm² was utilized for both 810nm and 1064nm wavelengths.

Comparison of 800 nm and 1064 nm Lasers:

  1. Mechanism of Action: Both 800 nm and 1064 nm lasers share a similar mechanism of action during the initial 4 minutes of PBM, as evidenced by dose-dependent increases in Δ[oxCCO] and Δ[HbO].
  2. Irradiance and Penetration: The 1064 nm laser had a higher measured irradiance (220 mW/cm²) compared to the 800 nm laser (190 mW/cm²), which was less collimated and attenuated more in peripheral regions.

Effects of 810 nm LED:

  1. Performance Compared to Lasers: The 810 nm LED, despite its broader and less focused light, significantly enhanced Δ[HbO] and Δ[oxCCO] at a moderate irradiance of 135 mW/cm². Its effects were dose-dependent and comparable to those of the 800 nm laser, though weaker due to its lower irradiance.
  2. Advantages: LEDs are cost-effective, safe, and easy to use, making them a practical alternative to lasers for PBM.
  3. Long-Lasting Effects: The 810 nm LED and 800 nm laser both maintained elevated Δ[oxCCO] levels for at least 5 minutes post-PBM, unlike the 1064 nm laser, where Δ[oxCCO] returned to baseline immediately after stimulation. The reason for this difference remains unclear and warrants further investigation.

Key Takeaways:

  • Irradiance Importance: An irradiance greater than 100 mW/cm² is critical for effective PBM, as it ensures adequate tissue penetration and stimulation.

In summary, this study demonstrates that both lasers and LEDs can effectively stimulate PBM, but their efficacy depends on irradiance, wavelength, and light penetration depth. The 810 nm LED, despite its lower irradiance, shows promise as a practical and effective tool for PBM applications.

The Role of Wavelength in PBM

The wavelength of light, measured in nanometers (nm), determines how deeply light penetrates biological tissues. For brain photobiomodulation, wavelengths in the red (600-700 nm) and NIR (800-1100 nm) ranges are most effective. These wavelengths can penetrate the scalp and skull to reach cortical and subcortical brain structures.

The NIR range, particularly around 810 nm, is often favored in brain PBM due to its superior tissue penetration. This wavelength optimally interacts with cytochrome c oxidase, a key enzyme in the mitochondrial respiratory chain, enhancing cellular energy production. This wavelength’s interaction with neurons can induce mitochondrial stimulation, promoting cellular energy production and neuroprotection.

The 1064nm wavelength is a promising candidate for brain photobiomodulation (PBM) due to its ability to penetrate marginally deeper into tissues compared to shorter wavelengths. However, the 1064nm light interacts strongly with water molecules, abundant in biological tissues, leading to loss of energy absorption by the mitochondria, the primary target for PBM therapy.

An irradiance higher than sunlight coupled with a wavelength in the 810nm-1100nm range is ideal for brain photobiomodulation.

Practical Applications and Considerations

For effective brain photobiomodulation, both irradiance and wavelength must be optimized. Devices with adjustable settings allow practitioners to tailor therapy to individual needs, ensuring that the light penetrates deeply enough without causing overheating or discomfort.

Key Recommendations:

  1. Irradiance: Aim for devices with an irradiance of at least 100 mW/cm² for brain PBM, significantly exceeding the levels provided by natural sunlight.
  2. Wavelength: Prioritize NIR wavelengths around 810 nm for optimal tissue penetration and mitochondrial stimulation.
  3. Treatment Protocols: Follow evidence-based protocols regarding session duration and frequency to achieve the desired outcomes safely.

Conclusion

Irradiance and wavelength are pivotal metrics in brain photobiomodulation. While natural sunlight provides some NIR light, its irradiance is insufficient for the targeted therapeutic effects required in PBM. Devices designed to deliver higher irradiance, along with optimal NIR wavelengths, ensure that light penetrates the scalp and skull effectively, reaching the brain tissue to stimulate healing and enhance cognitive function.

For those interested in exploring brain PBM, it is essential to select devices that adhere to these principles. By understanding the science behind irradiance and wavelength, users can make informed decisions to maximize the benefits of this innovative therapy.

  • Respiratory & Immune System Dysfunction: Breathing difficulties, increased susceptibility to infections.

Given the wide variety of symptoms and their overlapping nature, understanding GWI requires a closer look at what it means to have a multi-symptom illness.

What Is a Multi-Symptom Illness?

A multi-symptom illness is a condition where multiple, often unrelated symptoms occur together, affecting different body parts. This makes diagnosing and treating these illnesses more complex, as doctors need to address a range of symptoms that may not have a clear connection.

Gulf War Illness (GWI) fits into this category, as its symptoms span across various systems in the body—neurological, muscular, gastrointestinal, and more. This wide range of symptoms can make it difficult to pinpoint a single cause or treatment. 

Additionally, the symptoms vary greatly from person to person, meaning no two cases of GWI are the same, further complicating the management of the illness.

Current Research and Treatment Approaches

Ongoing research into Gulf War Illness (GWI) has focused on potential links to neuroinflammation and mitochondrial dysfunction, which may explain the wide range of symptoms affecting veterans. 

In 2019, the Vielight Neuro Alpha was used in a successful pilot study by the University of California San Francisco on Gulf War Illness. This pilot study on US veterans represents the first documentation of GWI symptom improvements after PBM treatments.

Another particularly promising study, Transcranial Photobiomodulation to Improve Cognition in Gulf War Illness, investigated the use of red/near-infrared light therapy (photobiomodulation) applied to the brain. The results showed cognitive improvements, especially in veterans with higher PTSD symptoms, suggesting that this treatment could enhance brain function and reduce PTSD symptoms.

Current Treatment Options and Challenges

Currently, treatment strategies for GWI primarily focus on symptom management, including pain relief, cognitive therapy, and lifestyle changes. 

However, veterans often face significant challenges, such as limited treatment options, difficulty accessing care, and the need for more targeted, effective solutions. 

As GWI remains a complex condition, continued research and support are essential to develop more personalized and efficient treatments, helping affected veterans manage their symptoms and improve their quality of life.

Can Photobiomodulation (PBM) Help Veterans with GWI?

Photobiomodulation (PBM) is a non-invasive therapy that has gained attention for its potential to support Brain wellness and neurological function, particularly in conditions like Gulf War Illness (GWI). 

PBM uses red and near-infrared light to stimulate cells, which can help reduce inflammation, enhance cellular energy production, and promote neuroprotection. 

These effects are particularly relevant for GWI, as it is believed that neuroinflammation and mitochondrial dysfunction contribute to the condition’s symptoms.

Scientific interest in PBM has grown due to its success in treating conditions involving chronic pain, fatigue, and cognitive dysfunction—key issues for veterans with GWI. 

As researchers continue to explore PBM’s benefits, it shows promise as a potential tool to alleviate some of the debilitating symptoms of GWI, offering hope for improved symptom management and quality of life.

What is regenerative medicine? https://www.vielight.com/blog/what-is-regenerative-medicine/ Tue, 12 Mar 2024 18:31:02 +0000 https://www.vielight.com/?p=45374

Is Photobiomodulation a Regenerative Medicine?

Regenerative medicine aims to restore damaged tissues and organs by stimulating the body’s natural healing processes. 

While treatments like stem cell therapy and tissue engineering are well known in this field, emerging technologies such as photobiomodulation (PBM) are gaining attention for their potential role in regeneration, particularly in Brain wellness and neurological recovery.

But is photobiomodulation a regenerative medicine? This article will explore PBM’s mechanisms, its ability to support cellular repair, and how it aligns with regenerative medicine principles. Read on to discover its potential benefits!

What Is Regenerative Medicine?

Regenerative medicine is a field of healthcare focused on restoring damaged tissues and organs by stimulating the body’s natural healing abilities. It aims to repair, replace, or regenerate cells, offering innovative solutions for conditions that traditional treatments may not fully address.

By leveraging biological mechanisms, regenerative medicine seeks to enhance recovery and improve long-term health outcomes. Its applications range from treating injuries and neurodegenerative diseases to promoting overall tissue regeneration and functional restoration.

Common Approaches in Regenerative Medicine

Regenerative medicine encompasses a variety of innovative approaches aimed at restoring function and promoting healing at a cellular level. 

Here are some of the most common strategies driving progress in this field.

  • Stem Cell Therapy – Uses stem cells to replace damaged tissues and promote regeneration.
  • Tissue Engineering – Combines biomaterials and cells to create functional tissues for medical use.
  • Biologics – Includes growth factors, proteins, and gene therapies to accelerate tissue repair and healing.

Could photobiomodulation be the next breakthrough in regenerative medicine? Let’s explore how it works.

How Photobiomodulation (PBM) Works

Photobiomodulation (PBM) is a non-invasive therapy that uses specific wavelengths of light to stimulate biological processes at the cellular level. When light penetrates the skin and reaches targeted tissues, it interacts with mitochondria—the energy centers of cells—enhancing their ability to produce ATP (adenosine triphosphate), the fuel necessary for cellular function and repair.

PBM plays a fundamental role in cellular repair and regeneration by boosting mitochondrial activity. It helps reduce oxidative stress and inflammation, two key factors in tissue damage and aging. 

Additionally, PBM has been shown to enhance neuroplasticity, improve circulation, and accelerate recovery, making it a promising tool in regenerative medicine, particularly for Brain wellness and neurological conditions.

Can PBM Be Considered Regenerative Medicine?

Research suggests that photobiomodulation (PBM) has significant potential in regenerative medicine, particularly for neurological conditions. 

Studies have shown that PBM may aid in stroke recovery by reducing inflammation and promoting cellular repair. Additionally, PBM has been linked to improvements in neurodegenerative diseases like Alzheimer’s and Parkinson’s, helping to enhance cognitive function and slow disease progression. 

Scientific findings further support PBM’s role in neuroprotection and tissue repair

A 2022 study published in Frontiers in Medical Technology (Near-Infrared Photobiomodulation of Living Cells, Tubulin, and Microtubules In Vitro) demonstrated that PBM influences cellular structures, promotes microtubule reorganization, and balances neural activity, key factors in brain regeneration. 

These findings reinforce the idea that PBM can help maintain Brain wellness, repair damaged neural networks, and enhance overall cognitive function.

Benefits of PBM in Regenerative Medicine

Photobiomodulation (PBM) is emerging as a powerful tool in regenerative medicine, offering a non-invasive approach to supporting tissue repair and Brain wellness. By stimulating cellular activity with near-infrared light, PBM helps improve cognitive function, accelerate recovery, and promote overall well-being. 

Here are some key benefits:

  • Improved Brain wellness and Neuroplasticity: PBM enhances cognitive function and mental clarity by promoting neuroplasticity—the brain’s ability to reorganize and form new connections. This can be beneficial for individuals recovering from neurological conditions or looking to optimize brain performance.
  • Enhanced Recovery from Injury: PBM helps reduce inflammation and oxidative stress, two major barriers to healing. By stimulating mitochondrial activity, it accelerates cellular repair, making it useful for recovery after brain injuries, strokes, or neurodegenerative conditions.
  • Non-Invasive and Safe Alternative: Unlike many regenerative therapies that require surgery or drug treatments, PBM offers a safe, non-invasive solution with minimal risks. It provides a scientifically backed way to support regeneration without the need for complex medical interventions.

Photobiomodulation’s potential in regenerative medicine is clear, but how can you integrate this groundbreaking technology into daily life? That’s where Vielight Neuro comes in.
