PTE Summarize Written Text

Read the passage and summarise it in ONE sentence. Sleep plays a central role in learning. During deep sleep, the brain replays experiences from the day and strengthens the connections between neurons that store new information. Studies in which students learned vocabulary before either sleeping or staying awake found that those who slept remembered significantly more the next day. Conversely, students who regularly sacrifice sleep to study late into the night may be undermining the very memories they are trying to form. Researchers therefore argue that schools should treat sleep as part of the learning process rather than as time taken away from it.
