    Working memory is responsible for the temporary manipulation and storage of information to support reasoning, learning and comprehension. During working memory tasks, modulation of different frequency band oscillations has been observed; however, a full explanation of this phenomenon is still needed. Background oscillations coming from subcortical structures drive a gating-like mechanism for working memory computations or states. It is also known that different frequency bands are associated with different computations carried out by working memory. Three well-known examples of this are: the storage of new information correlates positively with oscillations in the beta–gamma band, theta-band oscillations are directly linked to maintenance of information while ignoring irrelevant stimulations, and clearance of memory is associated with alpha-band oscillations. We propose a computational framework for the cerebral cortex that connects individual oscillatory bands to different working memory processes.
