Spectral light stimulation at one end of a nerve root produces a measurable increase in biophotonic emission at the opposite end, an effect that can be blocked by procaine or metabolic inhibitors, suggesting that light-induced biophotons travel along neural fibers, possibly via protein-protein biophotonic interactions.",
