Carnegie Mellon research provides insight into brain's decision-making process

[11 March 2010 - EurekAlert! - Carnegie Mellon University] Replaying recent events in the area of the brain called the hippocampus may have less to do with creating long-term memories, as scientists have suspected, than with an active decision-making process, suggests a new study by researchers at Carnegie Mellon University and the University of Minnesota Medical School. ... "Based on these observations, we have to rethink what is the role of replay for memory," wrote neuroscientists Dori Derdikman and May-Britt Moser of the Norwegian University of Science and Technology in a commentary also published in the March 11 issue of Neuron. They suggested that replay in the hippocampus may prove to have a dual role -- both for memory consolidation and for making cognitive maps of the environment. More
