Neuroanatomical associations of laughter identification accuracy across the patient cohort. Statistical parametric maps (SPMs) of regional grey matter volume positively associated with overall laughter identification accuracy and accuracy of identification of particular laughter subtypes (derived from a voxel-based morphometric analysis) are shown for the combined patient cohort (see also Table 2). SPMs are overlaid on representative sections of the normalised study-specific T1-weighted group mean brain MR image, thresholded at p < .05_FWE corrected for multiple voxel-wise comparisons over the whole brain. The MNI coordinate (mm) of the plane of each section is indicated and the left cerebral hemisphere is shown on the left for coronal sections and at the top for axial sections; the colour bars code T values for each SPM.
