Abstract

Peptide-containing neurons in the rat suprachiasmatic nucleus (SCN) were investigated by immunocytochemistry using specific antisera against vasoactive intestinal peptide (VIP), peptide histidine isoleucine amide (PHI), gastrin releasing peptide (GRP), and vasopressin. VIP-and PHI-like immunoreactivity coexisted in the
