Question

Quizplus · Accepted Answer

Overall brain volume and weight actually decrease in adulthood, so option D is false. A, B, and C are true. New neurons do continue to form in the adult brain, although at a slower rate than during development, and there is no significant loss of neurons in adulthood. Loss of neurons with aging is a normal part of the aging process and not necessarily a sign of pathology.
