Shared activity between periods of perceptual decision making and confidence report in Experiment 1. (a) Decision-related brain activity obtained from the contrast Decision > Cue. (b) Confidence report-related brain activity obtained from the contrast Confidence > Cue. (c) Intersection between the activation maps for perceptual decision making and confidence showing the areas of activation overlap. Colors indicate t-values. The t-values in (c) are the average of the Decision > Cue and Confidence > Cue t-values. The black borders delineate motor-related activations in the somatosensory, motor, and pre-supplementary motor cortex, while the white borders delineate all other regions. aPFC, anterior prefrontal cortex; dACC, dorsal anterior cingulate cortex; dlPFC, dorsolateral prefrontal cortex; dmPFC, dorsomedial prefrontal cortex; FEF, frontal eye field; IPS, intraparietal sulcus; OTC, occipitotemporal cortex; STG, superior temporal gyrus.
