State-Dependent Time-Sharing in the Developing Sensorimotor System, But Not the Visual System
Bottom row: A 20-minute segment of representative data from a P5 rat showing transitions between REM sleep (blue) and wake (red). Middle row: In the sensorimotor system, the limb movements characteristic of REM sleep (i.e., twitches) are qualitatively different from those during wake, made possible by state-dependent time-sharing of the system. Top row: No such time-sharing appears to occur in the visual system; as currently understood, retinal waves are triggered independent of sleep-wake state.
