An illustrated midsagittal section of the brain from a medial view, depicting areas of the brain which respond to pain, particularly in women. Typical regions of the brain (bottom-top) which have demonstrated a response to painful stimuli are the periaqueductal gray, thalamus, cingulate gyrus and primary somatosensory cortex. Recent studies have shown that there is significantly more activity in the anterior cingulate cortex in women when the brain registers pain, as compared to men. Some functions of the anterior cingulate cortex are to modify emotional responses or regulate impulse control, blood pressure and heart rate.
