Reciprocal interaction of sleep and synaptic plasticity.
Synaptic plasticity underlying learning and memory has been proposed, on the basis of several experimental approaches, to be intimately related with sleep: 1) The idea that sleep contributes to stabilization of acquired memory arises from numerous studies depriving subjects or animals of sleep. 2) Evidence from developing technologies supports "offline" reprocessing of recent experiences during sleep. 3) Recent analysis of the thalamocortical system establishes the reciprocal observation that sleep itself is a plastic process affected by waking experience. This overview synthesizes these converging perspectives across a variety of brain regions and species. We propose the developing visual pathway as a fruitful model for comprehensive understanding of sleep and synaptic plasticity.
