报告简介：

Memories of specific events are represented by distributed neural assemblies, or engrams.We propose that individual engrams consist of a multitude of representational formats that correspond to consecutive processing steps of these events. Reinstatement of engrams in different representational formats supports memory functions from short-term memory maintenance to long-term memory retrieval and memory consolidation. The presentation provides an overview about recent studies investigating the brain regions and oscillatory signatures that support reinstatement of engrams across representational formats. We also suggest that impairment of specific representational formats in neurological and psychiatric diseases can account for associated memory dysfunctions.
