Dr. Richard Soutar traces how photobiomodulation moved from pain-relief gadgets to brain-focused tools used alongside neurofeedback. He compares early near-infrared headsets such as Vielight with newer far-infrared helmets like Neuromatrix, explains why clinicians apply them before or after training (EMF noise), and sets realistic expectations for who may benefit—particularly people with TBI or early cognitive decline—while noting NewMind’s ongoing research.
