title: [Aminergic innervation of the hypothalamo-hypophyseal system in Gambusia sp. (Teleost, Poecilidae) studied by two fluorescence techniques].
abstract: Using fluorescence techniques (Falck-Hillarp, de La Torre and Surgeon) 2 paired groups of perikarya were observed in the hypothalamus of Gambusia, one in the nucleus recessus lateralis (NRL) and the other in the nucleus recessus posterioris (NRP). No fluorescent neuron could be detected in the nucleus recessus preopticus (NRPO) nor in the nucleus lateralis tuberis (NLT). Fluorescent aminergic fibers demonstrated in the rostral neurohypophysis and in the neurointermediate lobe might originate from the NRL. These two techniques are complementary, but the last one, more rapidly performed, appears promising.
