Many studies have clearly demonstrated benefits of trans-cranial application of low level light therapy (red and infrared wavelengths). This article goes over the main mechanisms involved which is based on photon energy absorption of cytochrome oxidase (a photoreceptor) Once these high energy photons transfer their energy to the these photreceptors of the brain, now allowing for cognitive enhancement and higher-order brain functioning. In addition, this energetic transference from these high energy light particles allows for neuroprotection, which can explain many previous studies on the benefits of light therapy for neurological conditions <view study>
