Memories could be lost if two key brain regions fail to sync together, study finds — ScienceDaily

Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study led by the universities of Bristol and Heidelberg has found.

How do you keep track of what to do next? What happens in the brain when your mind goes blank? Short-term memory relies on two key brain regions: the hippocampus and the prefrontal cortex. The researchers set out to establish how these brain regions interact with one another as memories are formed, maintained and recalled at the level of specific groups of neurons. The study, published in Currently Biology, also wanted to understand why memory sometimes fails.

“Neural assemblies” — groups of neurons that join forces to process information — were first proposed…
