[Neuronal activity of the ventromedial hypothalamus in motivated, emotionally positive and negative states].
In unrestrained rats, neuronal activity of the ventromedial hypothalamus (VMH) was studied in fasting, satiation and motivational-emotional states induced with electrical stimulation of the lateral hypothalamus (LH) and VMH. Three types of nervous cells were distinguished. The 1st-type neurons decreased their firing rate in satiation and revealed no obvious tendency in response to LH and VMH stimulation. The 2nd-type neurons enhanced their firing rate in satiation, were inhibited under motivational and emotionally negative stimulation effects. The 3rd-type neurons showed no response to either satiation or motivational states induced with LH stimulation, and were activated in emotionally negative states.
