Photoneuroendocrinology

Meaning

Photoneuroendocrinology is the specialized field of study investigating the intricate, causal relationships between light exposure, the nervous system, and the endocrine system, focusing on how photonic input regulates hormonal rhythms and neurochemical signaling. This discipline examines the biological mechanisms by which light, a critical environmental cue, governs circadian timing, seasonal reproduction, and mood regulation. It represents a synthesis of chronobiology, neuroscience, and endocrinology.
