Recollection-specific increase in theta-alpha power. A, Time–frequency plot of the relative change in power from baseline (REC − FAM) averaged across all channels that are part of the cluster (all except for one frontocentral channel) is shown on the left. Time–frequency samples not significant on any channel within the cluster are displayed opaque. The right plot shows the topographical distribution averaged across all time–frequency samples within 490–1500 ms and 4–13 Hz. B, Time–frequency plots of the relative change in power from baseline for all conditions. Data are averaged over all channels that are part of the cluster showing a significant difference for the contrast REC > FAM for REC (left), FAM (middle), and NEW (right).
