Oscillatory network rhythms are critical means for the interregional communication in the brain; they control information transfer, information filtering and synaptic plasticity in different behavioral states. In the hippocampus, two types of rhythms, gamma oscillations and sharp-wave ripples are generated, depending on the the level of cholinergic activation. We have identified molecular and cellular mechanisms that control the generation and propagation of these rhythms and their modulation by fear and anxiety.
