The Familiar Model of Memory – Forget It? (BBC News / Science)


Research on mice indicates that the decades-old orthodox dichotomy between short and long-term memory may be (partially) false.

Researchers at the Riken-MIT Center for Neural Circuit Genetics have discovered that memories are formed in the hippocampus and the cortex simultaneously; although the balance of priority shifts from the hippocampus to the cortex as time passes. Formation of long-term memories is impeded if connections between the hippocampus and the cortex are blocked.

The potential significance of these finding for dementia research is as yet unclear.
