In 20 cats spatial conditioned reflexes were elaborated manifested in the animal's stay on an "active" square of the floor attended in different sessions with stimulation (100 imp/s; 0.3 ms, 2 or 6 V) of the septum, the lateral hypothalamus or the hippocampus. Stimulation of the septum and lateral hypothalamus with a 2 V current resulted in an accelerated(More)
During prolonged electrical stimulation of the septum (self-stimulation 2-3 h daily for 2.5 months) perikarion of most neurons, situated around the tip of the stimulating electrode undergoes peripheral chromatolysis, less part of the neurons is shrunk, mitochondria are desorganized, invaginations of the nuclear membrane occur more often and deeper.(More)
The study of the self-stimulation of the brain, associated with the appearance of positive emotions, is essential in the investigation of the neurophysiological mechanisms of motivation [6, 13, 17]. Given the possibility of choice from many brain structures, the animal prefers the stimulation of the septum [5, 7]. In this case, it electrically stimulates(More)
