Brain Scan (IMAGE) Weill Cornell Medicine Caption The scan to the left shows brain activity (e.g., metabolism) in a premenopausal woman; the scan to the right shows brain activity in a postmenopausal woman. The color scale reflects brain activity, with brighter colors indicating more activity, and darker colors indicating lower activity. The scan to the right (menopause) looks 'greener' and overall darker, which means that the woman's brain has substantially lower brain activity (more than 30 percent less) than the one to the left (no signs of menopause).
