Your amazing brain and senses, sentence 13

For most of the 20th century scientists thought adults never grow new brain cells; now we know some new cells form in a few areas, and the brain makes new connections all life long.

Who acts: scientists, adults, we, new cells, brain · What happens: think, not grow, know, form, make · To what, where: new brain cells, few areas, new connections · Speech: someone speaks here
