Sleep-based memory processing facilitates grammatical generalization: Evidence from targeted memory reactivation.
Generalization-the ability to abstract regularities from specific examples and apply them to novel instances-is an essential component of language acquisition. Generalization not only depends on exposure to input during wake, but may also improve offline during sleep. Here we examined whether targeted memory reactivation during sleep can influence grammatical generalization. Participants gradua...
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...
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 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 کاملNo effect of odor-induced memory reactivation during REM sleep on declarative memory stability
Memory reactivations in hippocampal brain areas are critically involved in memory consolidation processes during sleep. In particular, specific firing patterns of hippocampal place cells observed during learning are replayed during subsequent sleep and rest in rodents. In humans, experimentally inducing hippocampal memory reactivations during slow-wave sleep (but not during wakefulness) benefit...
