Do animals dream? Twitching dogs, replaying rats and colour-changing octopuses, sentence 12

Scientists recorded rats' brains while they ran a maze and saw the same patterns again while the rats slept; this replay may help the brain store what was learned, but whether the rat experiences it as a dream is still argued.

Who acts: Scientists, rats, replay, brain, rat · What happens: record, run, see, sleep, help, store · To what, where: brains, maze, same patterns, brain · Speech: someone speaks here
