Syncing Brain Regions Crucial for Memory Retention, Chaos a Factor in Forgetting: Study

A new study led by the universities of Bristol and Heidelberg has found that if neural assemblies between the hippocampus and prefrontal cortex fail to sync together at the correct time, memories are lost. The study also wanted to understand why memory sometimes fails. Using brain recordings in rats, the research team has shown that memory encoding, storage, and recall are supported by dynamic interactions incorporating multiple neural assemblies formed within and between the hippocampus and prefrontal cortex.
