[Pattern and efferent paths of LRH neurons in primates (author's transl)].

LRH neurons have been studied by immunofluorescence on slides using rabbit immunoserum against unconjugated synthetic LRH. In Primates they form main groups localized in the medio basal hypothalamus, the septo-preoptic area, the anterior pericommissural area and the perimammilary region. They give rise, respectively, to the hypothalamo-infundibular LRH tract, the preoptico-terminal LRH tract, various extra-hypophyseal LRH tracts, ending in the telencephalon, the epithalamo-epiphyseal region and the mesencephalon.
