title: On track with two gammas.
abstract: CA1 place cells discharge in prospective and retrospective modes, possibly reflecting memory retrieval and encoding, respectively. In this issue of Neuron, Bieri et al. (2014) report that slow and fast gamma oscillations associate with prospective and retrospective discharge, indicating that gamma oscillations organize information-processing modes.
