    Abstract:
    Simultaneous electrical stimulation of the anterior part of the cingulate gyrus and the anterior-lateral part of the hypothalamus in the dog brought about EEG synchronization in the limbic system structures and increased correlation coefficients between them. The animal's behaviour exhibited positive emotionally reactions (licking, sniffing, wagging the tail), attended with slowing of the heart rate. The indicated changes directly depend on the degree of emotional stress (the changes are more pronounced in hungry than in sated animals). Simultaneous stimulation of the anterior part of the cingulate gyrus and the anterior-lateral part of the hypothalamus apparently activates a system which reduces the level of emotional stress.
