PET scans showing brain estrogen receptor (ER) density in a premenopausal (left) and a postmenopausal (right) woman. The color scale reflects brain ER density, with brighter colors indicating more receptors. The postmenopause scan looks ‘yellower’ and overall brighter, indicating that the woman’s brain has significantly more estrogen receptors than the premenopausal brain.
