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. Credit: Mosconi Lab The transition to menopause is marked by a progressively higher density of estrogen receptors (ER) on brain cells, a measure that remains elevated in women up to their mid-sixties, according to a new brain imaging study Read More
