Abstract

Recent studies in this laboratory have demonstrated the presence of two discrete populations of unusual catecholamine-containing cells, one bordering the infundibular recess and the other bordering the preoptic recess, in the hypothalamus of the toad Bufo marinus (McKenna and Rosenbluth, 1971, 1974; McKenna et al., 1973). The cytological characteristics of the two cell types revealed by fluorescence histochemical, electron microscopic and Golgi impregnation methods indicate that neither cell can be categorized as a typical central adrenergic neuron. Instead one appears to be a receptor cell while the other may serve a secretory role.
