(Institute of Science and Technology Austria) After a rat has repeatedly moved from one spot to another, the same neurons that fired while the rat moved 'replay' this firing while the rat is asleep. Previously, it was thought that replay patterns only correspond to trips rats had made repeatedly while awake. Writing in Neuron today, scientists at IST Austria show that also when rats roam around freely, the hippocampus replays during sleep, but it does so in a random manner.
