A study of the feeding and social behaviour of the "Macacus rhesus" monkey after direct electrical stimulation and telestimulation of different points of the amygdala and the hippocampus.

We examined first the behavior of a single animal (Macacus Rhesus), partially free to move on a Brady chair, before and after direct electrical stimulation of the amygdala and the hippocampus; then the social behavior of two animals, completely free to move in a large behavioral cage, before and after stimulation, by radio, of the amygdala. Certain ventromedial areas of the amygdala have a short and long term inhibitory effect on feeding and social behavior and the hippocampus has a short and long term facilitating effect on feeding behavior, especially during the after discharge.
