Neuroscience: Rewinding the memory record

Laura L. Colgin1 & Edvard I. Moser1

Top

How does the brain store sequences of experience? Clues come from brain recordings of rats running along a track. The animals' memories seem to be consolidated in an unexpected way as they rest between runs.

Memories develop in several stages. After the initial encoding of new information during learning, memories are consolidated 'off-line', seemingly while not being actively thought about, through a cascade of events that is not well understood.
