Evoked potentials as indicator of possible involvement of ventromedial hypothalamus and lateral nucleus of the amygdala in the formation of feeding behavior.
Electrical stimulation of the ventromedial hypothalamus in cats leads to the appearance of an additional component in the structure of evoked potentials of the amygdala lateral nucleus; this component disappears after discontinuation of food reinforcement (suppression of the conditioned reflex). It was concluded that the lateral nucleus of the amygdala and ventrolateral hypothalamus, the structures belonging to the system of defense behavior, can change their congenital characteristics depending on the situation, when involved in the feeding behavior system.
