Certain brain peptides and catecholamines function in acti-vating the hypothalamohypophysial-ovarian axis in both rabbits and rhesus monkeys. The natural stimulus for a surge release of GnRH is coitus in rabbits, whereas the initial excitatory signal is ovarian steroids in monkeys. Despite this contrast in initial signals, specific neurochemicals may serve as common stimuli for GnRH secretion in both species. Evidence is presented that one such substance is norepinephrine (NE), which is released from the mediobasal hypothalamus before, or simultaneously with, GnRH, although the latency in time between stimulus (co-itus/estrogen) and response (GnRH/LH release) is very different. Moreover, both stimuli activate NE gene expression in cells lo-...
