Brain Photobiomodulation

Meaning

Brain photobiomodulation (PBM) is a non-invasive therapeutic technique involving the delivery of red or near-infrared light photons to the cerebral cortex and deeper brain structures. This application aims to modulate neuronal activity, enhance cerebral blood flow, and improve cellular energy metabolism within the neural tissue. Within the context of hormonal health, optimizing brain function is critical because the hypothalamus and pituitary gland, central regulators of the endocrine system, reside in the brain and control hormonal release via the HPA axis. PBM seeks to support the neuroendocrine regulatory loops that govern systemic hormonal balance.
