from 1975 , we have carried the immunohistochemical study of several hypothalamic neuronal populations in the human fetus : lh-rh ( 1976 ) , somatostatin ( 1977 ) , pro-opiocortin ( 1978 ) , vasopressin and oxytocin ( 1979 ) , corticoliberin ( 1982 ) , somatocrinin ( 1983 ) , and hypothalamic neurons containing an unidentified peptide ( 1984 ) .
