Abstract: Simultaneous recordings from hippocampus and entorhinal cortex in rats show that as the animals learn odour guidance cues during their exploration of two-dimensional space in the laboratory, ensembles of coherently firing neurons emerge in both locations, with cortical–hippocampal oscillatory coupling occurring in a specific range of the beta-gamma frequency band.
