previous studies have shown that small discrete lesions of the periventricular hypothalamic ( pv ) and medial-basal amygdaloid ( amg ) nuclei , which contain high concentrations of somatostatin neurons , reduce somatostatin-like immunoreactivity ( sli ) in the median eminence ( me ) by approximately two thirds and one third , respectively .
