Neuro Duo 4  Vagus Combo


Discover the Vielight Neuro-Vagus combo, a pioneering system that merges brain stimulation with vagus nerve stimulation to enhance brain function, systemic performance, and brain-body connectivity. Additionally, the world-exclusive Vielight Neuro Duo offers transcranial-intranasal photobiomodulation (PBM) for cognitive, memory, and blood flow improvements.

As the world’s only transcranial-intranasal brain photobiomodulation (PBM) device, the Vielight Neuro Duo is is the result of years of engineering and research.

Clinical research with our technology has produced improvements in cognitionmemory and blood flow.

The Vielight Neuro Duo comes with both Alpha and Gamma modes.

  • Gamma (40Hz): focus, memory, brain energy.
  • Alpha (10 Hz): relaxation and sleep improvement.

Vielight technology quality is guaranteed by medical grade certification.

Unlock Your Brain's Potential with the Vielight Neuro Duo

The Vielight Neuro Duo represents a powerful and extensively researched brain photobiomodulation (tPBM) device, featuring cutting-edge intranasal technology. It's designed to be safe, effective, and exceptionally user-friendly, offering the potential to unlock your brain's capabilities. Our patented transcranial-intranasal technology provides a unique and potent approach to stimulating the Default Mode Network in the brain.

The Neuro Duo emits pulsed near-infrared (NIR) energy through the cranium, initiating the process of photobiomodulation. Our engineering prowess allows us to extract one of the highest levels of power (~100 mW/cm2) from a near-infrared LED energy source, all while ensuring there is no heat generated.

This innovative device operates at two crucial frequencies:

  1. Gamma (40 Hz): Linked to enhanced focus, improved information processing, memory boost, and increased mental energy.
  2. Alpha (10 Hz): Supports mindfulness, facilitates learning, promotes relaxation, and can contribute to improved sleep.

Choose the Vielight Neuro Duo to embark on a journey of brain stimulation, where you can potentially experience amplified focus, cognitive performance, memory enhancement, relaxation, and better sleep. Our rigorous research and cutting-edge technology combine to offer you a powerful tool to tap into your brain's potential.

  • Vielight technology quality is guaranteed by medical grade certification.
  • Vielight technology is supported by a two-year manufacturer’s warranty from the time of delivery.

Why the nose?
Being just 3 inches from the brain, the intranasal channel is the most efficient channel for photobiomodulation of the ventral (underside) brain area. These ventral structures within the brain’s core have important functions.


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.

Effects of the Vielight Neuro.

Default-mode network activity in

seed in the analysis

Comparing EEG Power Spectrum:

Active vs Sham tPBM Using Non-Parametric Cluster-Based Permutation Test.

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. (b) Difference between post and pre sham tPBM. (c) Difference between pre active and sham tPMB. (d) Difference between post active and sham tPMB.

tPBM's Impact on Resting-State EEG:

Active vs Sham Stimulation Compared by Frequency Bands.

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.

Vielight Vagus


The Vielight Vagus enables non-invasive vagus nerve stimulation (VNS) via photobiomodulation (PBM). This device was engineered to enhance brain-body connectivity via the vagus nerve.

The Vielight Vagus can be used together with the Vielight Neuro to complement and maximize outcomes.

Why the vagus nerve?

The vagus nerve is crucial in regulating many of our bodies’ most basic functions. One of the most important aspects of the vagus nerve is its direct connection between the brain and the gut.

Neuroplasticity: VNS has been associated with promoting changes in the brain’s structure and function, improving connectivity and neural network efficiency.

Cognitive Enhancement: Studies have explored the impact of VNS on cognitive functions. Some findings suggest improvements in memory, attention, and other cognitive domains.

Inflammation and Health: VNS has also been investigated for its potential effects on reducing inflammation and improving overall health outcomes.

Was super late but has finally arrived (Originally Ordered 3/2/24)

I've been using the Duo combo, and in all honesty, I can tell it works, but the devices are not comfortable at all. The head portion doesn't fit comfortably and presses too much on the forehead, where there should most likely be a cushion. The vagus nerve one also doesn't sit properly and falls off, it's hard to keep it on the side of the neck the directions say to place it, as it just slides off. I have two very old models of the nostril 633 and 810 from vie light years ago that sit comfortably still to this day when used; the nostril pieces for both the duo and the vagus are too tight and squeeze the nostrils - I'm not sure why vie light did this, it's painful and uncomfortable.
