This experiment extends Pavlov’s method of contrasts for 8 components of aggression were quantitatively evaluated in 11 freely moving adult cats. Aggression was elicited from the perifornix septohypothalamic areas by a series of progressively increasing and decreasing stimulation parameters. Three levels of thalamic stimulation (low, medium, and high) were combined with the perifornix stimulations. High level thalamic stimulation tended to facilitate the aggressive response elicited by low level perifomix stimulation. Thalamic lesions attenuated the aggression response, especially those elicited during high level perifornix stimulation. It was suggested that within the hypothalamic induced aggression circuitry the center median nucleus modulates the excitatory state of the system. The discussion concerns anatomic and physiologic pathways through which the center median nucleus may modulate the sensory, motor, and affective-autonomic subsystems into a well integrated aggressive state. These experimental findings are supported by the clinically established treatment of aggression by stereotaxic lesions placed in the center median nucleus.
