I review recent studies that support the hypothesis that rhythms facilitate functional interactions between the hippocampus and mPFC during behaviors requiring both regions. Owing to the complexities related to defining homologous areas of the prefrontal cortex across species [9,11], this review focuses on rodent studies. However, coherent oscillations in the hippocampus and mPFC are believed to mediate memory operations in humans (e.g. [12,13]) and other species also.
