Lesions of the amygdala impair the acquisition and expression of this learning. It alerts us to danger and activates the fight or flight response. Pharmacological and lesion studies of the basolateral, central, and medial subdivisions of the amygdala have shown that their activation induces anxiogenic effects, while their inactivation produces anxiolytic effects. However, if the amygdala takes over in such instances, a fight-or-flight reaction takes over. The stimulation was so low that it did not elicit an emotional response in patients, nor even an increase in heart rate or skin conductance. Scientists have discovered that men have a larger part of their brain devoted to emotional responses and a smaller region for logical thinking than women.
