Group differences in activation and multivariate patterns within insular subdivisions. (A) The three subdivisions of the insula as identified by cluster analysis (Deen et al., 2011) include the posterior insula (pI; white), the dorsal anterior insula (dAI; blue) and the ventral anterior insula (vAI; cyan). (B) Results from the univariate analysis of group differences in activation elicited by deviant faces vs scenes (Figure 3) showed overlap (green) with the vAI cluster. (C) Multivariate analysis of group differences in activation patterns elicited by deviant faces vs scenes (Figure 4) revealed prominent overlap (purple) with the dAI cluster.
