| Abstract: | Tested the social cohesiveness in an open field of 96 male hooded Long-Evans rats which had been subjected to either simultaneous or successive septal and amygdaloid lesions. Both the increased cohesiveness of Ss with septal lesions and the decreased cohesiveness of Ss with amygdaloid lesions were attenuated by the addition of the 2nd lesion. Ss with simultaneous lesions did not differ from controls. The 2 structures also were demonstrated to be reciprocally involved in mediating activity levels. (16 ref.)
