[Hypothalamo-bulbar regulation of afferent reactions of intact and altered heart].
Afferent reactions of the heart were studied by registration of evoked potentials (EP) in acute experiments on cats. It was established that the hypothalamo-bulbar structures take part in regulation of heart afferentation through depressive effects descending along the system of the vagus nerves. In this case increase of the activity of the posterior hypothalamus in the period of acute myocardial ischemia due to activation of neurons of the motor nucleus of the vagus nerves leads to depression of excitation processes on the neurons of the intracardiac nervous system, while the zones of the anterior hypothalamus exert a relieving effect on heart afferentation.
