The Vielight Neuro is designed for simplicity and home-use.

Our devices are auto-timed for 20 minutes. We do not recommend exceeding more than 20 minutes daily.

Alpha: For maintaining general brain health, recovering from stress, for relaxation and improved sleep quality.

Gamma: In preparation for tasks that require cognitive focus and improved creativity, addressing a decline in brain performance, helps with higher forms of meditation. Some may experience some sleeping difficulty if used before bedtime.

Duo: For individuals with healthy brains, we’d suggest using the Duo for four sessions per week. The Alpha can be used for the first three sessions (once every other day), followed by one Gamma session on the seventh day. For example, a user may undergo an Alpha session on Monday, Wednesday, and Friday, followed by a Gamma session on Saturday or Sunday.

If you have a healthy brain, use either version, once every 2 days.

If your brain isn’t healthy, use either version, once per day, 6 days a week.

One feature of PBMT that is becoming appreciated is the biphasic dose response (also known as the Arndt-Schulz law). This principle states that a very low dose of light has no effect, a somewhat bigger dose has a positive effect until a plateau is reached. If the light dose is increased beyond that point the benefit progressively decreases, until the baseline (no effect) is reached, and further increases, will actually start to have damaging effects on the tissue. This curve is well known in the field of toxicology, where the phenomenon is called “hormesis”. Part of the explanation of this “U” or “J” shaped curve is that small doses of a potentially toxic drug or harmful intervention can induce expression inside the cells of a range of protective factors such as anti-oxidant enzymes and anti-apoptotic proteins that will enhance normal function and protect against subsequent lethal challenges. Hence the “sweet spot” achieved with the 20-minute application time with the Vielight devices.

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.

Based on computer modelling, the 810nm wavelength has been found to be superior to other wavelengths that includes 1064 nm for penetration. This was proposed in 2018, and confirmed in 2020, by Harvard Medical School. Part of the explanation for the deeper penetration by 810 nm is the low absorbance by blood and water.

A recent study on vascular hemodynamics and cytochrome c oxidase redox activity by the Department of Bioengineering, University of Texas at Arlington examined the effects of different wavelengths within this range with

Lasers (800-1064nm | 250 mW/cm2 ) 810nm LED (135 mW/cm2)

Results

1. The 810 nm LED was able to create significant stimulations on vascular hemodynamic oxygenation and CCO redox metabolism despite the LED having a lower irradiance (≈135 mW/cm2)
2. The dose-dependent trajectory by the 810 nm LED was similar to that by the 800 nm laser.
3. The LED-triggered increases in Δ[oxCCO] remained at the elevated level without a returning tendency at least during the 5 min post-PBM period. In contrast, the increased Δ[oxCCO] by the 1064 nm laser started returning to the baseline immediately after the cease of the laser.

These findings are encouraging for us – our Vielight Neuro’s rear 810nm LED transcranial diodes generate ≈100 mW/cm2, which approaches the power density of ≈135 mW/cm2 used in the study. It underscores our commitment to fewer well-placed but sufficiently powerful diodes vs many weaker diodes.
