Researchers from Ruhr-Universität Bochum and the University of Bonn have investigated which activity patterns occur in the brain when people remember or forget things. They were interested in how the brain replays and stores during sleep what it had learned before. The team recorded the brain activity of epilepsy patients who had electrodes implanted into their brain for the purpose of surgical planning. One result: During sleep, the brain even reactivates memory traces that it can no longer remember later on.
Dr. Hui Zhang and Professor Nikolai Axmacher from the Department of Neuropsychology in Bochum describe the results together with Associate Professor Dr. Juergen Fell from the Department of Epileptology in Bonn in the journal Nature Communications, published on 5 October 2018.
