Sleep allows immune cells to do maintenance work on the brain

Studies have shown that during sleep, the brain reactualizes, updating memories, and clearing up “waste.” New research in mouse models suggests that specialized immune cells keep the brain in good working order by maintaining it during sleep.

New research in mice shows that immune cells are better able to perform maintenance work on the brain during sleep.

For instance, scientists have learned that the brain consolidates newly formed memories during sleep. They have also discovered that sleep provides an excellent opportunity to take out the neural “trash.”
