Disinhibition and external inhibition of response following septal lesions in rats.
Septal-lesioned and sham-operate rats were tested for reactivity to extraneous stimuli (clicks or flashing lights) presented during periods of low or high responding generated by a 120-sec FI schedule of reinforcement. While septal-lesioned rats tended to show greater disinhibition and less external inhibition than sham-operates, the magnitude of the deficits was not considered sufficiently great to warrant the conclusion that the septal syndrome results from increased susceptibility to disinhibition.
