Long-term sexual conflict situation induced changes in main statistical parameters of firing rate in the hippocampus, amygdala and septum both in intact rats and in those under stress. The latter were shown to reveal an increased number of the neurons with polymodal distribution of interspike intervals in all the structures under study.
Changes of unit activity in different nuclei of the posterior hypothalamus induced by intravenous oxytocin injections were studied in acute experiments on Wistar rats anaesthetized with nembutal. Influence of nonapeptide was dose-dependent. Latencies of various neuronal reactions were different. Mechanisms of oxytocin regulation of neuronal activity in the… (More)
