In humans and other mammals, the stillness of sleep is punctuated by bursts of rapid eye movements (REMs) and myoclonic twitches of the limbs.1 Like the spontaneous activity that arises from the sensory periphery in other modalities (e.g., retinal waves),2 sensory feedback arising from twitches is well suited to drive activity-dependent development of the sensorimotor system.3 It is partly because of the behavioral activation of REM sleep that this state is also called active sleep (AS), in contrast with the behavioral quiescence
