The role of serotoninergic neurons in rats agressive behaviour.
Lesions of the dorsal and medial raphe nuclei that caused a marked decrease of the 5-HT level in the forebrain induced in groupped rats intraspecies aggressiveness but failed to increase mouse-killing behaviour. In rats isolated for 3 weeks lesions of the raphe nuclei did not change behaviour of "killers" and natural "non-killers". The role of 5-HT in mechanism of the aggressive behaviour is discussed.
