Interspecies aggression in the rat: the role of the diagonal band of Broca.
Electrolytic lesions of the diagonal band of Broca were made in rats which had previously not killed mice (DBPt) and in rats which had no experience with mice prior to the beginning of the experiment (DBN). The lesions induced killing in 12 of the 20 naive (DBN) rats, but in only 1 of the 16 pretested (DBPt) rats. The region of the diagonal band is projected upon or has extensive projections to many regions of the central nervous system in which lesions have previously been found to induce muricide. The behavior induced by diagonal band lesions and lesions of these other regions was compared.
