Statistical parametric maps (SPMs) of regional grey matter volume associated with humour processing (shown here for the behavioural variant frontotemporal dementia group; see also Table 3). Correlates of processing familiar humour (relying on recognition of stock comedy situations, exemplified by farce) are coded in red and correlates of processing novel humour (relying on a psychological perspective shift, exemplified by satire) are coded in cyan. familiar detection, grey matter volume positively correlated with accuracy of detecting humour in familiar scenarios from humour decision task (see Table 2); novel detection, grey matter volume positively correlated with accuracy of detecting humour in novel scenarios from humour decision task. Results are overlaid on sections of the normalised study-specific T1-weighted mean brain MR image. The MNI coordinate (mm) of the plane of the section is indicated and the coronal section shows the right hemisphere on the right. SPMs are thresholded at p < .05 after family-wise error correction for multiple comparisons within small volumes of interest (see online material, Supplementary Fig. 1).
