In the world of brain enhancement discussion, photobiomodulation therapy (PBM), also known as low-level light therapy (LLLT) has attracted little attention but is quickly becoming a popular topic, particularly with the type of cognition-enhancing “laser light helmets” and full-body light panels I discuss on the podcast “Shining Laser Lights On Your Balls & Beyond: Photobiomodulation 101 – How To Use Near Infrared & Red Light For Collagen, Thyroid, Muscle, Skin & More.”
From a technical standpoint, PBM involves delivering light to the cells (including neurons) to modulate specific tissue functions. The cellular mechanisms of PBM have been well researched. Animal studies have shown cognitive improvements and recovery from brain insults of various kinds, including traumatic brain injury (TBI) and concussion. Most of the human studies have not been well controlled and to many serious scientists, have not shown sufficient reasons to be headlined or taken very seriously.
However, this is starting to change with a host of newer studies that you'll find linked in this article, and PBM is building its cache of merits to be recognized as a novel method to enhance brain functions, almost as a new kind of technological “nootropic.”
