Vielight Neuro Gamma 4: Transcranial Intranasal Brain Device

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 studies at Harvard Medical School and other leading universities point 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 context for how the technology was developed, rather than 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.
