Although our ability to transform an event episode into a permanent memory trace stands out as one of the most necessary of mental processes, the underlying brain mechanisms still remain poorly understood. This talk will outline emergent findings emphasizing the role of memory reactivation as a brain mechanism that helps address this computational challenge. The talk will cover research on healthy population and neurological patients, combined with EEG/MEG recordings, to guide and document the relevance of memory reactivation during working memory maintenance, memory recollection and sleep consolidation. Leveraged by the possibility that memory reactivation emerged as a mechanism bridging early stages of memory transformation and long-term memory representation, the talk will finally highlight recent data indicating that the rapid memory reinstatement of the just encoded sequence of episodic events influences how experience is carved and represented in long-term memory.
Targeted Memory Reactivation during Sleep Adaptively Promotes the Strengthening or Weakening of Overlapping Memories.
