TL;DR
Septal forebrain lesions produced an increase in the social rank of hooded rats and it appeared that the effects were due to the loss of previously acquired responses to other animals interacting with the sparing of a strong running response in the test situation.
Abstract
Septal forebrain lesions produced an increase in the social rank of hooded rats. Increase s in the frequency of both aggressive and defensive behaviors were obtained so that changes in social status could not be attributed to a simple increase in aggressiveness. It appeared that the effects were due to the loss of previously acquired responses to other animals interacting with the sparing of a strong running response in the test situation.
