To investigate this, we profiled the hippocampi of young and old mice in naive states and 3hr after contextual fear conditioning.</description><dates><publication>2026/07/19</publication></dates><accession>GSE303038</accession><cross_references><GSM>GSM9116189</GSM><GSM>GSM9116186</GSM><GSM>GSM9116185</GSM><GSM>GSM9116188</GSM><GSM>GSM9116187</GSM><GSM>GSM9116184</GSM><GSM>GSM9116191</GSM><GSM>GSM9116190</GSM><GPL>30172</GPL><GSE>303038</GSE><taxon>Mus musculus</taxon></cross_references></HashMap>
