Brain Bioenergetics

neuron photobiomodulation

Neurons are cells that contain mitochondria.

By utilizing the science of photobiomodulation to energize neuronal mitochondria, this triggers a cascade of beneficial cellular events.

Some potential effects are : neuroprotective effects, self-repair mechanisms and enhanced function.

Electromagnetic radiation within the NIR range carries the most potent form of photonic diffusion through tissue, blood and brain.

The 810nm wavelength exhibits the least photonic scattering and absorption by blood|water in the entire electromagnetic spectrum.

Clinical studies have shown that NIR radiation of sufficient power density is capable of diffusing through the scalp, skull and brain to depths of 4 cm or more, transcranially and through the intranasal channel.

The Vielight Intranasal Advantage

Vielight’s patented intranasal stimulation technology and microchip LED technology is a powerful tool for brain photobiomodulation.


The intranasal channel lacks hair and skin, which are natural barriers for light energy.

Being just 3 inches from the brain, the intranasal channel is the most efficient channel for photobiomodulating the deeper, ventral brain area.

These deep structures within the brain’s core have important functions, such as long term memory and hormonal regulation.

In-Depth Summary

Mechanisms of Brain Photobiomodulation

There are several mechanisms associated with promoting physiological change through photobiomodulation therapy (PBMT). The wavelengths primarily used with PBM is within the near-infrared range of the electromagnetic spectrum with a sufficient power density. When hypoxic/impaired cells are irradiated with low level NIR photons, there is increased mitochondrial adenosine tri-phosphate (ATP) production within their mitochondria.1, 2 Another change is the release of nitric oxide from the hypoxic/impaired cells. Neurons are cells that contain mitochondria and nitric oxide.

In hypoxic neuronal cells, cytochrome-C oxidase (CCO), a membrane-bound protein that serves as the end-point electron acceptor in the cell respiration electron transport chain, becomes inhibited by non-covalent binding of nitric oxide. When exposed to NIR photons, the CCO releases nitric oxide, which then diffuses outs of the cell – increasing local blood flow and vasodilation.3, 4

Following initial exposure to the NIR photons, there is a brief burst of reactive oxygen species (ROS) in the neuron cell, and this activates a number of signaling pathways. The ROS leads to activation of redox-sensitive genes, and related transcription factors including NF-κβ.5, 6 The PBMT stimulates gene expression for cellular proliferation, migration, and the production of anti-inflammatory cytokines and growth factors.7

Vielight Neuro Alpha | Vielight Neuro Gamma

The Neuro Alpha and Neuro Gamma are next-generation transcranial-intranasal brain photobiomodulation headsets, with varying pulse frequencies.

These devices utilize state-of-the-art microchip technology to boost photonic 810nm power density within the transcranial clusters, reaching 300% of the power output of the original Neuro. Our engineering team has downsized equivalent technology into the intranasal diode.

Each session is auto-timed for 20 minutes, resulting in specific total irradiation with near-infrared photons of sufficient power density per cycle.


  • The 10 Hz pulse rate correlates with alpha brainwave oscillations and overall enhanced cellular light absorption for overall neuronal photobiomodulation.


  • The 40 Hz pulse rate correlates with gamma brainwave oscillations and specifically, enhanced memory function and cognition.
