Abstract: Information flow in the hippocampus In neuronal networks, the gamma frequency oscillation is thought to be important for several higher-end cognitive processes, such as attention and memory. Coordinated firing by widely distributed cells is required to produce an oscillation, but this network activity can be quite variable. It is not clear why gamma oscillations should differ so greatly across time and space. New evidence reveals that information trafficking within the hippocampus and parts of temporal cortex is dependent upon the speed of gamma. Faster oscillations link entorhinal cortex to CA1, providing information on the animal's location, while slower oscillations link CA1 to CA3 for information storage. Thus, one possible function underlying a variable gamma is to properly route information within a circuit.
