mouse nerve cell stimulation

MISS MATCH  After paw stimulation, nerve cells in the brain of a 7-day-old mice become active (top row, left), but blood doesn’t show up (bottom row, left). A 13-day-old mouse has larger nerve cell responses (top row, middle), but still no blood — that doesn’t appear until adulthood (bottom row, right). Red signals higher nerve cell activity and blood flow.
