What is Photobiomodulation?

The brain is the most important and complex human organ. Within every brain cell are mitochondria, which are best understood as the energy-producing “powerhouses” of the brain. Through biochemical reactions, the mitochondria create fuel for brain cells. 

Your brain’s mitochondrial performance can be improved by absorbing light energy (photons) of specific wavelengths. This process is called photobiomodulation or PBM. Scientific research shows our brain’s mitochondria respond positively to light energy within the NIR wavelength range.

When NIR energy from, for example, a Vielight Neuro, is delivered to neuronal mitochondria, it is absorbed by a light-sensitive enzyme called cytochrome c oxidase. This enzyme uses NIR energy to start a series of biochemical reactions that are both beneficial and energizing to the neurons and other brain cells.

Collectively, brain photobiomodulation heals damaged brain cells, improves cerebral blood circulation, reduces inflammation and toxicity, and regenerates damaged brain cells. In a nutshell, NIR light energy delivered to the brain improves efficiency and performance due to better signaling and repaired connectivity between the neurons.

The NIR spectrum of light energy provides the deepest penetration into brain tissues which also results in benefits. We chose the NIR wavelength of 810 nm based on the NIR window. To determine the optimal parameters for PBM, research that uses Vielight technology often employs brain imaging and brain signaling techniques.

Brain Bioenergetics

Neurons are cells that contain mitochondria.
By delivering photons to a light-sensitive enzyme(cytochrome c oxidase) found within the mitochondria, this triggers a cascade of beneficial and energizing cellular events.
Some potential effects are : enhanced cognition, neuroprotective effects, self-repair mechanisms
