Engram cells retain memory under retrograde amnesia

A long-standing hypothesis about memory storage is that memory engram is stored in a form of strengthened connections between respective engram cells, with process of synapse modification occurring during periods of memory consolidation. In this study, Ryan et al. unexpectedly show that amnesia caused by consolidation blockade does not prevent memory retrieval driven by optogenetic activation of dentate engram cells. These results change our perspective on how memory traces are stored in the brain.
