Memory formation finding

Here's an interesting finding about memory formation.

The widely held belief is that short-term memories are first formed in the hippocampus and over time they move to the prefrontal-cortex, the store-house of long term memories. However, in a recent experiment researchers discovered that, at least in mice, memories were established in both locations simultaneously, although  prefrontal-cortex memories would remain silent for a few days before they were matured and activated.

The finding doesn't turn current thinking on its head, excuse the pun, as there is constant communication between these two parts of the brain, but the idea that the cortex is utilised from the get-go is certainly an interesting development in our understanding of memory formation.
