Figure 3 (IMAGE) Japan Science and Technology Agency Caption Diagrammatic model showing orchestration of ensembles of engram cells across memory processing. Many sub-ensembles express during experiencing novel episode. A part of sub-ensembles of engram cells re-appear during post-episode experience sleep. This set of sub-ensembles appeared during sleep are more likely observed during memory retrieval. In contrast, control, non-engram, cells almost do not show this feature.
