Hippocampal sharp-wave ripples in cognitive map maintenance versus episodic simulation.

Abstract

Hippocampal sharp-wave ripples (SWRs) have been proposed to support memory-based decision-making. A new study by Gillespie et al. (in this issue of Neuron) provides important new insights on how past experiences and future choices are reflected in neuronal activity during SWRs.
