Men And Women Respond Differently To Stress

The University of Pennsylvania School of Medicine is reporting research that shows that different parts of the brain are activated in males and females when confronted with a stressful situation. The researchers examined the activity of participant's brains using fMRI while exposed to stress.

You may not know it, but your levels of stress hormones are probably rising. Ditto for your heart rate. In animals, stress can stunt growth, slow learning, or fluster the immune system. In people, chronic stress can cause high blood pressure, among other problems.
Test subjects were asked about their state of stress and anxiety between MRI scans. While stress and anxiety showed similar trends, stress was even higher after the hard math task.

Neuroscientists Find That Men And Women Respond Differently To Stress

April 1, 2008 — Functional magnetic resonance imaging of men and women under stress showed neuroscientists how their brains differed in response to stressful situations. In men, increased blood flow to the left orbitofrontal cortex suggested activation of the "fight or flight" response. In women, stress activated the limbic system, which is associated with emotional responses.
