Dr. Laura Colgin published a review paper in Current Opinion in Neurobiology entitled “Theta-gamma coupling in the entorhinal-hippocampal system”. Theta rhythms (∼5–10 Hz) have been thought to play a critical role in memory processing in the entorhinal–hippocampal network. However, recent evidence suggests that successful memory performance also requires coupling of ∼30–100 Hz gamma rhythms to particular phases of the theta cycle. This review outlines the hypothesis that such theta–gamma coupling may facilitate transfer of information throughout the entorhinal–hippocampal network and serve to facilitate either memory encoding or memory retrieval.
