Reactivating Memories for Consolidation
The consolidation of memory is thought to occur via a hippocampal-neocortical dialog involving reactivation of memory patterns in the hippocampus during sharp-wave ripples. In this issue of Neuron, Nakashiba et al. demonstrate that CA3 output is required for consolidation of contextual fear memory. They also show that lack of CA3 output results in a decrease in ripple-related reactivation, prov...
متن کاملStrengthening individual memories by reactivating them during sleep.
While asleep, people heard sounds that had earlier been associated with objects at specific spatial locations. Upon waking, they recalled these locations more accurately than other locations for which no reminder cues were provided. Consolidation thus operates during sleep with high specificity and is subject to systematic influences through simple auditory stimulation.
متن کاملConsolidation of temporal order in episodic memories
Even though it is known that sleep benefits declarative memory consolidation, the role of sleep in the storage of temporal sequences has rarely been examined. Thus we explored the influence of sleep on temporal order in an episodic memory task followed by sleep or sleep deprivation. Thirty-four healthy subjects (17 men) aged between 19 and 28 years participated in the randomized, counterbalance...
متن کاملConsolidation of Episodic Memories During Sleep
Two experiments investigated the long-term effects of retrieval practice. In the retrieval-practice procedure, selected items from a previously studied list are repeatedly recalled. The typical retrieval-practice effects are considerably enhanced memory for practiced items accompanied by low levels of recall, relative to baseline, for previously studied items that are associated with the practi...
متن کاملConsolidation and Reconsolidation: Two Lives of Memories?
Most studies on memory consolidation consider the new information as if it were imposed on a tabula rasa, but considerable evidence indicates that new memories must be interleaved within a large network of relevant pre-existing knowledge. Early studies on reconsolidation highlighted that a newly consolidated memory could be erased after reactivation, but new evidence has shown that an effective...
