[The effect of ablation in the n. medianus raphe on the aggressive and sexual behavior of white rats].
A study was made of a change in the aggressive and sexual behaviour of albino rats under the influence of ablation of the n. medianus raphe whose serotonin-containing units send ascending projections to the forebrain. Ablation of the nucleus produced a drop in the serotonin level in the forebrain, and aggressiveness to mice, which was much more pronounced in the male than in the female animals. Intraspecial aggressiveness between animals of the same sex and the sexual behaviour of the male rats did not change. It has been assumed that n. medianus raphe exerts an inhibitory influence on the manifestation of aggression of the "predatory" animal.
