Figure 2. Contribution of adrenal hormones to the opposite effects of stress on learning in males versus females. A. Males adrenalectomized (ADX) prior to stressor exposure were not affected by stress, while those exposed to a sham surgery showed an enhanced response rate. B. In contrast, females adrenalectomized (ADX) prior to the stressor exposure showed impaired response after stress, as did the females exposed to a sham surgery.
