Table 2. Brain regions correlating with behavioral provocation effect.
Region of activation | Laterality | Coordinates | r-value |
Run 1: high>low provocation (outcome) | |||
Insula | R | 45, 11, 16 | 0.76 |
Middle frontal gyrus (BA 10) | R | 36, 41, 16 | 0.77 |
Inferior frontal gyrus (BA 47) | R | 27, 23, −11 | 0.74 |
Caudate body | R | 12, 14, 7 | 0.75 |
Medial frontal gyrus (BA 32) | R | 6, 11, 46 | 0.77 |
The covariate analysis regarding the outcome phase of the first run and correlations with the behavioral provocation effect yielded several regions defined by correlation (p<0.0001, uncorrected for multiple comparisons; FDR q<0.02) and size (10 or more voxel). The stereotaxic coordinates of the peak of the activation are given according to Talairach space together with the r-value for the cluster peak.
