Intramodal searchlight analysis. Left, Group‐average classification accuracy for sounds, videos, and touches. Auditory stimuli were most accurately decoded in the auditory cortices, peaking along Heschl's gyrus. Visual stimuli were most accurately decoded in the calcarine sulcus and occipital pole. Tactile stimuli were most accurately decoded along the pre‐ and postcentral gyri. Successful classification, for each modality, also extended beyond the respective sensory cortices, into the association cortices as well as the early sensory cortices of the other modalities. Maps were thresholded at the P level of 0.01 (t > 2.567; DOF = 17) and then a cluster mass P level of 0.05, as determined by a nonparametric one‐sample t‐test (5,000 permutations of random sign‐flipping of the data). Right, Overlaps among the intramodal classifications. A crossmodal overlap score was calculated by summing the normalized accuracy values of the input maps and selecting only the shared voxels. Auditory and visual stimuli were jointly best decoded in parietal operculum, supramarginal gyrus, posterior temporal cortex, and temporal and occipital fusiform gyri. Auditory and tactile stimuli were jointly best decoded in planum temporale, parietal operculum, and supramarginal gyrus. Videos and touches were jointly best decoded in superior parietal lobule, supramarginal gyrus, parietal operculum, and lateral and inferior occipital cortex. Stimuli from all three modalities were jointly best decoded in the parietal operculum, supramarginal gyrus, and secondary somatosensory cortex, as well as lateral and ventral occipital cortices.
