Effects of medial septal stimulation on hypothalamically-elicited intraspecific attack and associated hissing in cats

Stimulation of the medial region of the cat septum facilitates intraspecific attack and associated hissing elicited from the ventromedial hypothalamus. This facilitative influence did not extend to lateral hypothalamically-elicited predatory attack, nor do the data indicate a suppression of predatory attack coincident with facilitation of intraspecific attack.
