- Travels easily with headset, intranasal applicator, charger, and carry case included
Five modules reaching the brain from two directions
The Neuro Alpha runs a single 810 nm wavelength, chosen because near-infrared passes through tissue more readily than visible light. Four modules sit against the scalp and one applicator sits in the nasal channel, a route that surface-facing light cannot take, covering roughly 400 cm2 in all. The light pulses at a fixed 10 Hz, a hardware setting and not a claim about brain rhythms.
The 10 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:
- Photomedicine and Laser Surgery, 2017. 5 older adults, 12 weeks The first published case series of the transcranial plus intranasal design used 810 nm light pulsed at 10 Hz, the Neuro Alpha setting, and reported improved cognition scores and better sleep, with no adverse effects.
- Scientific Reports, 2019. 20 healthy adults, single 20-minute session The same headset design pulsed at 40 Hz 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 headset 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.

Recommended pairing
The Neuro Alpha aims 810nm light at the brain for calm; the X-Plus 4 takes a different pathway for the body. Its 633nm nasal applicator and 810nm thymus module support systemic immune wellness in a matching 20-minute session.

Description
Included with purchase: six months of partial access to Vielight-AI, free with your Neuro 4.
The Vielight Neuro Alpha is a brain photobiomodulation device that delivers gentle, pulsed near infrared light to the brain to support relaxation, calm, and stress relief. It pairs a full transcranial headset with Vielight's patented intranasal module, an approach that reaches deeper brain regions than headset only devices can.
Alpha mode, for a calmer mind
The Neuro Alpha pulses 810nm near infrared light at 10Hz, the frequency associated with the brain's alpha rhythm. Alpha activity is linked to a relaxed, settled mental state, making this the model oriented toward calm, stress relief, and supporting healthy sleep.
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 Alpha
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 struggle is switching off at night, not staying sharp by day; that is the Alpha side of the split.
- Sessions pair well with something still, like reading or meditating; they do not mix with moving around.
- You can keep a near-daily 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
- Mornings and a faster paced session style suit you better; the Neuro Gamma 4 is that model.
- Want both pulse modes on a single device? That is the Neuro Duo 4.

How to use
- Set upSeat the four transcranial modules on the scalp so the concave lenses part the hair for direct contact, then insert the intranasal applicator into one nostril before starting a session.
- SessionRun one timed 20-minute session; the 10 Hz Alpha pulse is described by Vielight as promoting a relaxed, calming mental state. Vielight suggests it is best used at nighttime, just before bed.
- Frequency of useVielight suggests starting from every other day up to six days a week depending on your needs, with a general recommendation of daily use.
- CareThe intranasal applicator is a personal-contact part; keep it clean and replace as needed (Vielight sells spare intranasal applicators separately).
- Good to knowVielight says do not use with active brain bleeds or a history of seizures, and that pregnant women should consult their healthcare provider before using photobiomodulation. It notes possible mild, temporary effects such as headache, dizziness, or slight discomfort at the application site.

Why it earns a place in the stack. Most routines train the body and leave the mind to fend for itself. The Neuro Alpha covers that gap, pulsing 810nm near infrared at the brain's relaxed alpha rhythm through scalp and nasal channel during a single 20-minute hands-free session. That dual pathway 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.
