Summary of VBM correlates of sarcasm identification in patient groups.
| Behavioural Correlate |
Brain region | Cerebral hemisphere | Cluster size (voxels) | p value |
|---|---|---|---|---|
| Combined groups | Anterior TL, OFC | R | 107,453 | 0.02 |
| bvFTD only | Anterior TL, OFC | Bilateral | 318,805 | 0.01 |
| bvFTD > svPPA | Parahippocampal, fusiform gyri | L | 61,222 | 0.03 |
Voxel-based morphometry (VBM) associations of TASIT total sarcasm identification score are summarised. All correlations shown are positive and significant after family-wise error correction for multiple comparisons at whole brain level (p < 0.05). bvFTD, behavioural variant frontotemporal dementia; L, left hemisphere; OFC, orbitofrontal cortex; R, right hemisphere; svPPA; semantic variant primary progressive aphasia; TL, temporal lobe.
