Vielight, Neuro Gamma 4
Transcranial-intranasal brain photobiomodulation device · 40 Hz Gamma
Focus and mental energy come down to how efficiently your brain produces energy, and that is exactly what brain photobiomodulation is designed to support. The Neuro Gamma 4 is the world's only transcranial-intranasal brain photobiomodulation device, delivering pulsed 810 nm near-infrared light at the 40 Hz gamma frequency through both the cranium and the intranasal channel. Gamma oscillations correlate with focus, information processing, memory, and brain energy, and this is the same Vielight Neuro technology featured across independent brain PBM research worldwide.

Focus is not about trying harder. It is about brain energy.
Mental clarity, focus, and recall all run on one thing: how efficiently your brain cells produce energy. Your brain is roughly 2% of your body weight and burns about 20% of your energy, and the mitochondria inside your neurons are the engines doing that work.
When that energy production runs low, the experience is familiar. The afternoon fog. Re-reading the same sentence three times. Walking into a room and forgetting why. Reaching for another coffee, not because you want it, but because you cannot think without it.
Most people treat that as a willpower problem. It is closer to an energy problem. And for decades, the only levers most of us had were stimulants, sleep, and hoping for a better day.
"Brain photobiomodulation has become one of the most actively researched approaches to supporting brain energy, and the Vielight Neuro technology is featured across independent brain PBM research publications worldwide. The device is built to medical-grade quality standards: ISO 13485, MDSAP, and TÜV Rheinland safety certification."
Research context only. This device is not a treatment for any medical condition.
Most of the tools we reach for never touch the brain directly.
- Stimulants borrow against tomorrow. Caffeine and energy drinks push you through the afternoon, then the crash arrives, and the dose has to climb to keep working.
- Willpower runs out. "Just focus harder" works until the brain is genuinely low on energy. Then no amount of effort moves the needle.
- Supplements feed the body, not the brain network directly. Useful, but they do not deliver energy to the neurons doing the thinking.
- Sleep is the one real fix, and the one nobody has enough of. When rest falls short, most people have nothing left to reach for.
None of these reach the brain where the work happens. One technology was built to do exactly that.
Meet the Vielight Neuro Gamma 4.
The world's only transcranial-intranasal brain photobiomodulation device.
The Neuro Gamma 4 is a next-generation, at-home, drug-free brain photobiomodulation (PBM) device. It transmits pulsed near-infrared light energy to support the brain's natural energy production, no pills, no stimulants, no heat.
It is built on Vielight's proprietary Vie-LED technology and patented intranasal technology, which together deliver industry-leading energy density. Two channels work at once: transcranial modules send light through the cranium, while the intranasal applicator reaches the ventral brain from just 3 inches away. Together they are designed for comprehensive stimulation of the Default Mode Network.
The session is simple. You wear the headset, place the intranasal applicator, and let it run. That is the whole protocol.
Drug-free and at-home
No prescription, no clinic, no stimulants.
Pulsed 810 nm at 40 Hz gamma
The frequency associated with focus and brain energy.
Transcranial plus intranasal
The only device that reaches the brain through both channels.
No heat
Cold LED diodes deliver substantial power without warming the skin.
Light the brain can use.
Your neurons produce energy in their mitochondria. Brain photobiomodulation is the process of delivering specific wavelengths of near-infrared light to those cells, where the light energy is absorbed and, in research, has been explored as a way to support cellular energy production.
The Neuro Gamma 4 transmits pulsed near-infrared (NIR) energy through the cranium, activating this photobiomodulation process. Through efficient engineering, it extracts one of the highest power outputs available from an NIR source, around 100 mW/cm², without generating heat.
This is a figure from published research. It illustrates study findings, not results you should expect from using this device.
810 nm, chosen for depth
The 810 nm wavelength has the deepest penetration through tissue and bone, enabling light to reach toward the neuronal mitochondria. This is why Vielight selected it.
40 Hz, the gamma frequency
The light pulses at 40 Hz, which correlates with neural gamma oscillations. Gamma brain waves correlate with focus, information processing, memory, and brain energy levels.
Why the nose
The intranasal channel sits just 3 inches from the brain, making it an efficient path for photobiomodulation of the ventral (underside) brain area, where several core structures live.
"810 nm near-infrared, pulsed at 40 Hz gamma, delivered through the cranium and the nose. Cold light the brain is designed to absorb, with no heat at the skin."

Gamma for focus. Alpha for calm. Duo for both.
All three Vielight Neuro 4 devices share the same Vie-LED engineering, 810 nm wavelength, transcranial-intranasal design, and medical-grade certifications. The difference is the pulse frequency, and what that frequency is designed to support.

One session. Two channels. Done in minutes.
Position the headset
Place the Neuro headset so the modules sit in direct contact with your scalp for maximum energy transmission.
Insert the intranasal applicator
The applicator reaches the ventral brain through the nasal channel.
Run the session
Power on and let the device do the work. Near-infrared light is nearly invisible, so the beam looks dimmer than its actual power density. That is normal.
Repeat on your schedule
Build the habit at the frequency that suits you.
Refer to the included user guide for full instructions. Consult your physician before starting, especially if you have a medical condition, are pregnant, or have photosensitivity.
