title: Brain biology: jerked around by sleep.
abstract: During rapid eye movement sleep, the forelimb muscles of newborn rats jerk and twitch in an organized pattern, the fidelity of which improves with time. The coordinated nature of such sleep movements may instruct the developing brain how to more effectively execute movements during wakefulness.
