[Effect of stimulation of emotiogenic zones of the rat hypothalamus on the course of pregnancy and the growth of the progeny].

The course of pregnancy and progeny development was studied in white rats with different emotional background during pregnancy. Self-stimulation of emotionally positive zones of the lateral hypothalamus and forced stimulation of emotionally negative zones of the ventral hypothalamus were taken as models of emotional states. Stimulation or self-stimulation of these structures, while causing unidirected negative effect on pregnancy and progeny, affected in different ways the speed of conditioning in viable progeny. Stimulation of emotionally negative zones of the ventromedial hypothalamus in the last third of pregnancy caused an acceleration of conditioning in the progeny. The self-stimulation of emotionally positive zones of the lateral hypothalamus failed to produce such effect.
