| Bo Lei, Li Lv, Shiqiang Hu, Yikai Tang, Yi Zhon. Social experiences switch states of memory engrams through regulating hippocampal Rac1 activity. Proceedings of the National Academy of Sciences of the United States of America. vol 119. issue 15. 2022-04-04. PMID:35377811. |
here, we show that social experiences stimulated switching between latent and silent engrams to achieve flexible memory accessibility and also reveal the basic molecular mechanism of: 1) social reward turning silent engram to latent via suppression of rac1 activity in ca1 neurons of the hippocampus; and 2) social stress switching latent memory engram into silent through activating rac1. |
