Neuro Gamma 3 (Brain)
As the world’s only transcranial-intranasal brain photobiomodulation (PBM) device, the Vielight Neuro is is the result of years of engineering and research. The Vielight Neuro’s powerful, patented transcranial-intranasal technology offers an unparalleled advantage for reaching the ventral and cortical layers of the brain.
The Neuro Gamma pulses light at the 40 Hz frequency. This frequency is similar to neural gamma waves. Gamma waves are correlated with increased memory activity, perception, cognition and creativity.
The patented combination of transcranial and intranasal neurostimulation makes the Neuro Gamma ideal for comprehensive brain photobiomodulation, by simultaneously stimulating the ventral and cortical brain areas.
Powerful yet simple, the Vielight Neuro Gamma features microchip-boosted transcranial LED diodes, which generate sufficient power to penetrate the skull (Link). Furthermore, the Neuro Gamma’s refined form factor allows it to fit a wider variety of head shapes and sizes.
At present, our engineering team is able to extract one of the highest amounts of power in the world from a near-infrared LED energy source.
Why the nose?
Being just 3 inches from the brain, the intranasal channel is the most efficient channel for photobiomodulation of the underside (ventral) brain area.
These ventral structures within the brain’s core have important functions.
Difference between the Alpha and Gamma
- The Vielight Neuro Gamma’s 40 Hz pulse rate correlates with EEG gamma brain oscillations. This pulse rate differs from the 10 Hz pulse rate of the Vielight Neuro Alpha.
- The scientific reasoning behind the difference between the 655 nm and 810 nm wavelengths can be found in this independent study : (Link)
- Near-infrared light is nearly invisible to the naked eye, making the beam appear dimmer than its power density.

Please note that this device is not the same as the Neuro RX Gamma that is currently being used in our clinical trials. The RX Gamma is intended to be fully compliant with regulatory requirements for a medical device and will not be available without regulatory clearance. The “Neuro RX Gamma” is therefore a different product from the “Neuro Gamma”.

Vielight Neuro FAQ
What wavelength does the Vielight Neuro emit?
The Vielight Neuro emits 810nm NIR energy.
Why the 810nm wavelength?
The 810nm wavelength has the deepest penetration through tissue and bone, enabling photonic diffusion to the brain.
What is the difference between the Duo, Gamma and Alpha models?
The Gamma model pulses NIR light energy at 40 Hz, which has a neuromodulating effect on Gamma neural oscillations. Theoretical benefits are increased memory activity, perception, cognition.
The Alpha model pulses NIR light energy at 10 Hz. This frequency is similar to neural alpha waves. Alpha waves are correlated with the brain’s resting state, offering support for mental coordination, mindfulness and learning.
The Duo makes both of these pulse rates available to you – having both pulse rates brings the most benefits.
How much power do your devices generate?
Our devices generate sufficient power to penetrate the skull and produce statistically significant results in independent research and clinical studies. For a full list of our published results, please refer to this link: Link
What is the recommended usage?
The general recommended usage is to use once every other day before experimenting with more frequent usage, not exceeding once per day. For more serious cognitive impairment, the recommendation is once per day, six days a week. Please note these recommendations are theoretical, anecdotal by nature and only based on published data or ongoing clinical trials with yet unpublished results.
Engineering behind the Vielight Neuro.
The Vielight Neuro enables direct contact with the scalp’s surface to maximize energy transmission and penetration while microchip-boosted cold LED diodes generate substantial power without releasing heat. Additionally, our patented intranasal technology enables photobiomodulation of the ventral brain areas.

Non-parametric cluster-based permutation test comparing the rest EEG power spectrum between active and sham tPBM. Topographical maps are color-coded according to the permutation tests t-values. Clusters of electrodes with significant difference between the two conditions are marked in ‘+’ sign (p < 0.05 and αcluster = 0.01). (a) Difference between post and pre active tPBM.

Influence of tPBM on resting-state electroencephalography. Box plot illustrates the median and range of power spectrum across all electrodes for each oscillatory frequency bands. (a) Effect of active tPBM on power spectrum pre (green line) and post (red line). (b) Effect of sham tPBM on power spectrum pre (green line) and post (red line). (c) Difference between Active and Sham tPBM: Change of power spectrum Post-Pre for active (red line) and sham (green line) tPBM. Active versus sham stimulation revealed significant lower alteration in delta and theta power and higher change in alpha, beta and gamma frequency bands. (Link)
