Ontogenic studies of the neural control of adenohypophyseal hormones in the rat: Gonadotropins
1. Serotonergic, dopaminergic, and opioid systems controlling luteinizing hormone (LH) and follicle stimulating hormone (FSH) secretion develop with particular characteristics in the male and female prepubertal rats. 2. Serotonergic pathways evoke a maximal release of LH and FSH in female rats from...
