| summary | Working memory processes can consist of a variety of sub-functions, such as target selection and distracter suppression, active encoding processes, maintenance, mental manipulation of stored memories, matching of memory entries with incoming sensory information, etc. Here we will provide evidence that some of these sub-processes might be dissociable when looking at oscillatory brain processes, and specifically neural synchronisation patterns. The role of distributed, synchronised theta activity (rhythmical brain activity around 5 Hz) for encoding of targets into visual working memory will be discussed. Sustained interaction between theta and gamma (oscillations beyond 30 Hz) frequencies during retention of visual information in working memory will be argued to reflect active maintenance processes. And transient phase synchronisation between slow and fast brain rhythms will be introduced as mechanism for matching of stored information with sensory input. |
