Figure 4.

Evolution of whole-session power and coherence during training. A, The progression of median theta power and coherence values across the progressive session training steps, averaged across rats in each group. ELS animals showed enhanced theta power in all structures during response training (solid arrows). B, Progression of median gamma power and coherence values across the session training steps. Control but not ELS animals showed an increase in CA3–CA1 coherence over the DNMS steps (dashed arrow).
