Extended Data Fig. 2: Within-task temporal generalization of decoding of stimulus category.

a, iEEG within-task temporal generalization decoding of category (faces-objects) for pattern classifiers trained and tested on task-relevant stimuli. As in Fig. 2b, columns represent stimulus durations (left: 0.5 s; center: 1.0 s; right: 1.5 s) and rows represent theory ROIs (top: posterior; bottom: prefrontal). Contoured red-shaded regions depict significant above-chance (50%) decoding. Here and below, significance was evaluated through a cluster-based permutation test (p < 0.05; two-sided). Sample size as in Fig. 2. b, iEEG within-task temporal generalization decoding of category for task-irrelevant stimuli. Conventions as in a. c, MEG within-task average decoding of category (faces-objects), for the task-relevant (orange) and the task-irrelevant (purple) conditions, in posterior (left) and prefrontal (right) ROIs. Underlying lines depict significantly above-chance (50%) decoding assessed by cluster-based permutation test (p < 0.05). Error bars depict 95% CI estimated across participants. d, MEG within-task decoding of category (letters-falsefonts). Conventions as in c. e, fMRI searchlight decoding of category (faces-objects), collapsed across durations, for the task-relevant (left, orange) and task-irrelevant (right, purple) conditions. Outlined colors indicate regions on the inflated cortical surfaces showing significantly above-chance (50%) decoding (top: left/right lateral views; bottom: right/left medial views). f, iEEG ROIs decoding accuracies, collapsed across durations, within the task-relevant (left, orange) and the task-irrelevant (right, purple) stimuli. Same conventions as in e, with maps from a left lateral (top left), posterior (top right) and left medial (bottom) views. Brain surfaces in panels e,f are from Freesurfer.
