摘要: Using two different mRNA synthesis inhibitors, we show that blockade of hippocampal gene expression during restricted posttraining or postretrieval time windows hinders retention long-term spatial memory for the Morris water maze task, without affecting short-term memory, nonspatial learning, functionality hippocampus. Our results indicate consolidation induces activation transcriptional machinery and suggest existence a expression-dependent reconsolidation process operates in dorsal hippocampus at moment retrieval to stabilize reactivated mnemonic trace.
