Fig. 1: Task paradigm and functional localization of electrode sites in three networks of interest.

a The Gradual-Onset Continuous Performance Task. City and mountain scene images (from the SUN database⁹⁹) faded continuously from one image to the next every 800 msec. Trial onset (orange arrow) was the time at which stimulus fade-in was initiated. b Omission and commission error rates, averaged across runs, in 31 subjects. c Anatomical locations of cortical electrode contacts in 31 subjects, projected to fsaverage standard space and overlaying the Yeo atlas’ DMN (blue), DAN (green), and SN (red). d High-frequency broadband (HFB; 70–170 Hz) responses during the presentation of mountain (target) stimuli. Time courses show the grand average of the trial-wise means within all responsive electrodes (p < 0.05, cluster-based permutation test, corrected for multiple comparisons within networks within subjects) across the entire patient cohort. e Relative proportions of electrodes within each network showing significant target-evoked HFB increase (top) and decrease (bottom). f Locations of responsive electrodes within each network (fsaverage space). g Subdural electrodes plotted on the cortical surface with an overlay of the Yeo atlas’ DMN (blue) and DAN (green) in an example subject. Time series plots illustrate diverging HFB response profiles among neighboring electrodes (peak-responsive electrodes in the dPPC and PMC, respectively, are outlined in green and blue). Where relevant, error bars indicate standard error of the mean.
