Several investigations suggest that the amygdala plays a significant role in behavioral inhibition. Brutkowski, Fonberg and Mempel (1960) reported that bilateral lesions of the amygdaloid complex in dogs severely impaired inhibitory conditioned responses, while excitatory conditioned responses remained unaffected. Bilateral lesions of the amygdala have also been shown to impair the acquisition of the conditioned emotional response (Kellicutt & Schwartzbaum, 1963), and the retention of an auditory frequency discrimination in a bar pressing situation for food (Schwartzbaum, Thompson & Kellicutt, 1964). In the latter study, amygdaloid lesioned rats typically persisted in responses that were no longer adaptive, that is, they increased responding under nonreinforced conditions. [...]
