Abstract
LHRH [luteinizing hormone releasing hormone] neurons were studied by immunofluorescence on slides using rabbit immunosera against unconjugated synthetic LHRH. In man they form 4 main groups localized in the medio basal hypothalamus (infundibular nucleus, post-infundibular eminence, premammillary nucleus), the preopticoterminal area, the septum (and pericommissural area), the retromammillary area and the rostral mesencephalon. They give rise, respectively, to the hypothalamo-infundibular LHRH tract, the preoptico-terminal LHRH tract and to various extra-hypophyseal LHRH tracts, ending in the epithalamic area, the telencephalon and the mesencephalon.
