How the Gamma spreads 810 nm across the head
The Neuro Gamma delivers one 810 nm wavelength, a near-infrared band that moves through tissue more readily than visible light. Four scalp modules and one nasal applicator spread it across roughly 400 cm2, adding a route through the nasal channel that surface light does not reach. What sets this model apart is a fixed 40 Hz pulse, a hardware setting and not a claim about brain rhythms.
The 40 Hz pulse is a design setting, not a claim about brain activity; light supports normal cellular processes and does not treat, cure, or prevent any condition.
Three peer-reviewed studies. What they found.
Vielight's transcranial plus intranasal approach has been studied in independent, published research. Three studies, in brief:
- Scientific Reports, 2019. 20 healthy adults, single 20-minute session 810 nm light pulsed at 40 Hz, the Neuro Gamma setting, measurably shifted brain activity on EEG compared with a sham session: alpha, beta and gamma power rose while delta and theta fell.
- Photobiomodulation, Photomedicine and Laser Surgery, 2019. 8 older adults, 12 weeks of home use Participants using the Neuro Gamma at home three times a week showed increased cerebral blood flow and stronger connectivity within the brain's default mode network on MRI, alongside improved scores on standard cognitive assessments.
- Photomedicine and Laser Surgery, 2017. 5 older adults, 12 weeks The first published case series of the transcranial plus intranasal design reported improved cognition scores and better sleep, with no adverse effects.

Recommended pairing
The Neuro Gamma covers cognition, aiming 810nm light at the brain for focus and mental energy in a 20-minute session. The X-Plus 4's own 20-minute session sends 633nm and 810nm light to the nasal vasculature and thymus for whole-body immune support.

Description
Included with purchase: six months of partial access to Vielight-AI, free with your Neuro 4.
The Vielight Neuro Gamma is a brain photobiomodulation device that delivers gentle, pulsed near infrared light to the brain to support focus, mental energy, and cognitive performance. It pairs a full transcranial headset with Vielight's patented intranasal module, an approach that reaches deeper brain regions than headset only devices can.
Gamma mode, for focus and energy
The Neuro Gamma pulses 810nm near infrared light at 40Hz, the frequency associated with the brain's gamma rhythm. Gamma activity is linked to focus, information processing, and mental energization, making this the model oriented toward concentration, recall, and feeling sharp.
Why intranasal and transcranial together
Vielight's patented intranasal transcranial approach is what sets the Neuro apart. The headset delivers light across the skull with a focus on the Default Mode Network, the brain's central resting network, while the intranasal module sends light through the nasal channel to reach deeper structures the skull would otherwise block. Together they give a comprehensive brain energy footprint that transcranial only devices cannot match.
Why 810nm
The Neuro uses the 810nm wavelength because it offers the deepest penetration through tissue and bone. Head to head comparison research points to 810nm for the strongest tissue penetration and mitochondrial interaction, which is why Vielight built its technology around it.
The research behind Vielight
Vielight has the most published independent research in the field of brain photobiomodulation, with over 35 published and ongoing clinical trials behind its technology. We share this as background on how the technology was developed, not as a promise of specific outcomes.
Using your Neuro Gamma
Sessions are simple and hands free, and the device is designed for comfortable home use. It comes with the headset, intranasal applicator, charger, and carrying case.
Contraindications and use
Vielight devices are well tolerated by most people. They are not recommended for anyone with active brain bleeds or a history of seizures. If you are pregnant, consult your healthcare provider before use. Some users notice mild, temporary effects such as a headache or slight discomfort, which generally subside as the body adjusts.

Is this right for you?
You'll get the most from it if
- Your goal sits on the day side: staying sharp through work hours more than falling asleep faster.
- A session can share time with quiet desk work or planning; it does not suit moving around the house.
- You can hold a steady rhythm, from every other day up to six days a week.
- Thick hair is not a problem; the concave lenses part hair for direct scalp contact.
Maybe look elsewhere if
- Evening sessions before bed are more your style; look at the Neuro Alpha 4.
- Undecided between the two rhythms? The Neuro Duo 4 includes both 10 Hz and 40 Hz.

Why it earns a place in the stack. Most routines train the body and leave the mind to fend for itself. The Neuro Gamma covers that gap with a hands-free 20-minute session, pulsing 810 nm light at the brain's 40 Hz gamma rhythm while the intranasal module reaches regions a headset alone cannot.

Our approach
Every product earns its place.
No single thing changes your biology on its own. What matters is the system, and whether each piece earns its place. Here is how a device makes it into Kove.
01
Start with the evidence
Where there is research behind how something works, we read it. We look at the real mechanism a device relies on, like the wavelength, the frequency, or the dose, and whether the evidence holds up. Substance comes before marketing, and we are honest about how strong that evidence is.
02
Separate mechanism from marketing
A claim is not a mechanism. We check a device's real output against its stated one: does the panel emit the 660 and 850nm it advertises, at the irradiance that makes those numbers matter? The marketing language gets set aside. The measurable spec is what we judge.
03
Verify build and dose
Even a good idea does nothing if the hardware is weak. We confirm the output is consistent, the dose is usable in a real daily routine, and the build holds up over years, because a device only helps if it lasts as long as the habit.
04
Held to one standard
What clears every step earns its place in the system, held to the same standard as everything else. That consistency is what you can count on.
