Gender differences in the brain may explain why women and men often react differently to stress. Researchers studied the brains of male and female rats, focusing on two regions known to play a role in learning and stress: the amygdala and the prefrontal cortex.
The amygdala, a small almond-shaped structure located deep within the brain, senses stressful situations. The prefrontal cortex, in the front of the brain, is necessary for higher cognitive functions. Females can learn after stress if the prefrontal cortex can't 'talk' to the amygdala. The conclusion is that males and females can use different brain circuits to learn after stressful life events.
