Fig. 4: Network-specific profiles of task-evoked HFB activity during and preceding behavioral errors.

a High-frequency broadband responses during the presentation of mountain (target) stimuli, split into trials with correct and incorrect behavioral responses. Time courses show the grand average of the trial-wise means within all task-responsive electrodes (p < 0.05, cluster-based permutation test, corrected for multiple comparisons within networks within subjects). b Mean HFB power amplitude within the − 400 to 0 ms window relative to target onset. c Mean HFB power amplitude within the + 400 to + 1200 ms window relative to target onset. In b and c, bars show the mean of normalized HFB within all task-responsive electrodes (averaged across trials) within a given network, and error bars indicate standard error of the mean across electrodes. Upper lines and asterisks indicate significant effects (p < 0.05, Satterthwaite’s approximation) based on F tests of linear mixed model analyses (see Methods). Error bars indicate standard error of the mean.
