(Left) Time-resolved and trial-averaged values for delta power (upper), phase (middle), or HFA (50–200 Hz) power (lower). Shaded areas show standard error of the mean. Time-resolved difference scores for each neural measure are plotted below each panel and are conceptually similar to DS values reported in Figure 3 and Figure 1—figure supplement 1, with the following exceptions. Power values were compared between conditions using a two-sample t-test and significant differences between conditions were assessed for all neural measures using trial-label permutation testing (n = 1000 shuffles, p < 0.05). (Right) HFA windows, color coded by 1 Hz phase, for each category. Note that although some categorical information can be recovered when considering delta power, phase, or HFA power, these effects do not correspond to HFA time windows and more categorical information exists in the phase at which HFA windows occur (i.e., PAC, Figure 3B lower).
