Abstract

Midbrain raphe lesions induced aggressive behavior which was characterized by defensive aggression rather than offensive aggression in nature. Furthermore, raphe-lesioned rats exhibited muricide. This muricide included not only mouse-killing but also mouse-eating behavior. Both dorsal and medial raphe lesioned (dm-R) rats exhibited much greater hyperemotionality than either the dorsal (d-R) or medial raphe lesioned (m-R) rats, though no significant difference was found between d-R and m-R rats. It is concluded that the characteristic of aggression induced by raphe lesions is different in many respects from that induced by p-chlorophenylalanine administration, olfactory bulbectomy and septal lesions.
