The Neuro Duo 4 helps you improve your cognition, memory and functional connectivity. Its Alpha mode induces a more relaxed mental state while its Gamma mode induces a more focused mental state.
The Vagus was engineered to enhance brain-body connectivity and improve the brain-gut connection. Vagus nerve stimulation also promotes changes in the brain’s structure and function.
Using both devices together helps you with:
20 minutes per session
Results in 4 to 8 weeks
Adjustable and comfortable
The Vielight Neuro also offers patented intranasal photobiomodulation technology.

This is the best way to deliver near-infrared energy through the nose to the underside of the brain.
The olfactory bulb is directly connected to the brain regions responsible for keeping long-term memories.
The ventromedial prefrontal cortex is vital for cognitive processes.
The Vielight Neuro 4 has 5 Vie-LED modules that emit pulsed 810nm near-infrared light at 10 Hz (Alpha mode) and 40 Hz (Gamma mode) to stimulate the brain cells without generating heat.
The Vielight Neuro 4’s energy geometry is engineered to intentionally overlap broadened fields over Default Mode Network (DMN) nodes with the highest independently measured irradiance in commercially available brain photobiomodulation devices, while still bathing the wider cortex. This is why five VieLED modules can produce an effect that is effectively full‑transcranial, with a focus on the DMN.
The Vielight Vagus combines bilateral neck modules designed to engage the vagus nerve from both sides and an intranasal applicator. The device features a resilient, flexible steel band that self-adjusts to various neck sizes, ensuring a secure and consistent fit for every user.
The Neuro Duo 4 comes with:

Filter by benefit:
We have over 35 published and ongoing clinical trials with Vielight technology. The Neuro has been used in research such as:
Alzheimer’s disease (Dementia)
Parkinson’s disease
PTSD
Traumatic brain injury
Autism
Cognitive creativity
Neuromodulation
Cellular enhancement
The Neuro Duo 4 grants access to both the Alpha and Gamma pulse rates.
The Gamma mode pulses near-infrared light energy at 40 Hz, which has a neuromodulating effect on Gamma brain waves. This increases focus, information processing, memory, and brain energy levels.
The Alpha mode pulses near-infrared light energy at 10 Hz, which has a neuromodulating effect on Alpha brain waves. This has effects on the brain’s resting state, offering support for mindfulness, learning, relaxation, and sleep improvement.
Our general recommendation is to use both devices once a day, 6 days a week. They are timed for 20 minutes per session.
When it comes to the Neuro Duo 4, we recommend alternating between Alpha and Gamma modes. The Gamma mode is best used in the morning or early afternoon. The Alpha mode is ideal for nighttime and just before going to bed.
If you have any additional questions about usage, you can get a free consultation with our experts.
Vielight products are safe and well-tolerated by most users. However, there are some contraindications and potential side effects to be aware of:
Contraindications:
We don’t recommend using our devices if you have active brain bleeds or a history of seizures. Pregnant women should also consult with their healthcare provider before using photobiomodulation devices.
Side effects:
Some users may experience mild and temporary side effects, such as headaches, dizziness, or slight discomfort at the application site. These usually subside as the body adjusts to the therapy.
If you have any additional questions, feel free to reach out to us!
The Vie-AI Platform utilizes artificial intelligence (AI) and machine learning (ML) models to analyze EEG files with breakthrough precision and speed.
Whether you are a researcher, a clinician, or a home user, analyze your EEG data to learn how your brain reacts to brain photobiomodulation on the Vie-AI platform.
A soft launch is planned for early 2026.
Please note: To obtain EEG data, you will require an EEG acquistion device, such as Muse, Brainbit, Emotiv, Brainmaster etc.
