Awake reactivation predicts memory in humans.
How are new experiences transformed into memories? Recent findings have shown that activation in brain regions involved in the initial task performance reemerges during postlearning rest, suggesting that "offline activity" might be important for this transformation. It is unclear, however, whether such offline activity indeed reflects reactivation of individual learning experiences, whether the...
متن کاملMemory reactivation and consolidation during sleep.
Do our memories remain static during sleep, or do they change? We argue here that memory change is not only a natural result of sleep cognition, but further, that such change constitutes a fundamental characteristic of declarative memories. In general, declarative memories change due to retrieval events at various times after initial learning and due to the formation and elaboration of associat...
متن کاملTargeted Memory Reactivation during Sleep Depends on Prior Learning.
STUDY OBJECTIVES When sounds associated with learning are presented again during slow-wave sleep, targeted memory reactivation (TMR) can produce improvements in subsequent location recall. Here we used TMR to investigate memory consolidation during an afternoon nap as a function of prior learning. PARTICIPANTS Twenty healthy individuals (8 male, 19-23 y old). MEASUREMENTS AND RESULTS Partic...
متن کاملClosed-Loop Targeted Memory Reactivation during Sleep Improves Spatial Navigation
Sounds associated with newly learned information that are replayed during non-rapid eye movement (NREM) sleep can improve recall in simple tasks. The mechanism for this improvement is presumed to be reactivation of the newly learned memory during sleep when consolidation takes place. We have developed an EEG-based closed-loop system to precisely deliver sensory stimulation at the time of down-s...
متن کاملMemory stabilization with targeted reactivation during human slow-wave sleep.
It is believed that neural representations of recent experiences become reactivated during sleep, and that this process serves to stabilize associated memories in long-term memory. Here, we initiated this reactivation process for specific memories during slow-wave sleep. Participants studied 50 object-location associations with object-related sounds presented concurrently. For half of the assoc...
