摘　　要：In the structure of brain the medial preoptic area (MPO) and ventromedial nucleus of hypothalamus (VMN)are the two parts where the estrogen receptors concentrate but have opposite effects on sexual behavior. Recently estrogen receptors have been known to be located in the locus coeruleus(LC), where noradrenergic(NE) fibres terminate in the hypothalamus arising from cell bodies. The discharge rate of NE-ergic neurons in LC can be increased by electrical stimulation of MPO in a female rat at estrus stage, and decreased at diestrus stage. These studies help us to infer that VMN might have some modulation influence on NE-ergic neurons in LC. In order to study the pattern activities
