Experience-dependent slow-wave sleep development.
Sleep enhances plasticity in neocortex, and thereby improves sensory learning. Here we show that sleep itself undergoes changes as a consequence of waking experience during a late critical period in cats and mice. Dark-rearing produced a robust and reversible decrement of slow-wave electrical activity during sleep that was restricted to visual cortex and impaired by gene-targeted reduction of NMDA receptor function.
