Decoding the memory trace using multivariate analysis of electrophysiological data

There are strong clues that our memory is based on the reactivation of neural representations which are also active when we are perceiving a stimulus. These representations can be measured in terms of neural oscillations of various frequencies. This research examines the reactivation hypothesis by predicting using measured brain activity which neural representations are active during a memory task. The used methods inform about the brain regions that are involved during reactivations. They therefore provide new insight into the function of the memory system and potential associated pathologies such as Alzheimers disease.
