| Outline of Final Research Achievements |
We investigated whether the memory of maternal separation (MS) during early life is recalled. In order to address this issue, we tried to manipulate the memory engram induced by MS by irreversibly labeling the activated neurons during MS and re-activate these neurons by using optogenetic method. Furthermore, we analyzed maternal behaviors in the offspring suffered from MS. We found that these female offspring showed disorder of maternal behaviors including nest making, retrieving, etc., which caused higher death rate (more than 85%) in the neonatal period than control group.
