Comparing Models of Sleep-dependent Memory Consolidation
Research over the last half century has demonstrated that memory is not unified but is instead composed of anatomically and mechanistically distinct processes.1 The greatest dissociation is between memories that depend on the hippocampus versus those that do not. Hippocampal-dependent memories, also called declarative or explicit memories, are memories for people, places, or things; memories th...
متن کاملSleep-dependent memory consolidation and reconsolidation.
Molecular, cellular, and systems-level processes convert initial, labile memory representations into more permanent ones, available for continued reactivation and recall over extended periods of time. These processes of memory consolidation and reconsolidation are not all-or-none phenomena, but rather a continuing series of biological adjustments that enhance both the efficiency and utility of ...
متن کاملAge-related decline of sleep-dependent consolidation.
Sleep-dependent memory consolidation is observed following motor skill learning: Performance improvements are greater over a 12-h period containing sleep relative to an equivalent interval without sleep. Here we examined whether older adults exhibit sleep-dependent consolidation on a sequence learning task. Participants were trained on one of two sequence learning tasks. Performance was assesse...
متن کاملSleep-Dependent Learning and Memory Consolidation
While the functions of sleep remain largely unknown, one of the most exciting and contentious hypotheses is that sleep contributes importantly to memory. A large number of studies offer a substantive body of evidence supporting this role of sleep in what is becoming known as sleep-dependent memory processing. This review will provide evidence of sleep-dependent memory consolidation and sleep-de...
متن کاملSleep-dependent memory consolidation and accelerated forgetting
Accelerated long-term forgetting (ALF) is a form of memory impairment in which learning and initial retention of information appear normal but subsequent forgetting is excessively rapid. ALF is most commonly associated with epilepsy and, in particular, a form of late-onset epilepsy called transient epileptic amnesia (TEA). ALF provides a novel opportunity to investigate post-encoding memory pro...
