Learning-dependent changes in oscillatory power at θ and γ rhythms in CA1 and DMS. A, Changes in the oscillatory power (averaged for all rats) between the retrieval and acquisition periods for θ and γ rhythms. ***p < 0.0001. B, C, Oscillatory power changes in CA1 (B) and DMS (C) for the different frequency bands across different events between the learning stages: O, Opening of start box; S, start box exit; E, end of track; T, touchscreen response; Fi, entering food tray; Fo, exiting food tray. Oscillatory power changes across individual rats are also shown beside the averaged graphs. Note the differences in ordinate scales.
