Fig. 2

These two exemplary iEEG channels were simultaneously recorded from the same subject (P8). a Selected iEEG channel located in the DMN (specifically in the posterior cingulate cortex). The iEEG channel location (yellow crosshairs) is shown in subject-specific brain slices (axial–top, sagittal–middle, coronal–bottom). b Trial-averaged spectrograms (Ntrials = 60) for external–internal attention switching (upper plot) and internal–external attention switching (lower plot). The task switching occurred at time t = 0 s. c, d Same notation as in a and b for a selected channel from the DAN (specifically in the intraparietal sulcus). The DMN and DAN channels show nearly opposite activation patterns.
