^aCoordinates x, y, and z in space of MNI template and selection of cluster maxima according to the conventions of SPM8. The reported p values refer to cluster level inference and are familywise corrected for multiple comparisons. We report the decoding accuracy of the searchlight at each t peak and the average decoding accuracy over all searchlights within clusters.
