Chemical anatomy of the hypothalamus.
The neuropeptide field has witnessed considerable research interest over the past decade, and a growing body of anatomic, biochemical, and electrophysiologic data have since emerged, supporting the existence and putative neuromodulatory function of a large variety of these peptide hormones in several extrahypothalamic brain regions. It is now evident that neuropeptides not only fulfill criteria required of putative neurotransmitters, but more generally act as modulators of neuronal activity. The author discusses vasopressin and oxytocin pathways, corticotropin releasing factor, atrial natriuretic factor, thyrotropin releasing hormone, somatostatin, motilin, growth hormone releasing factor, dopamine, gonadotropin releasing hormone, and substance P.
