Location and size of clusters of vertices that showed significant SR>AL activation for the controls (n=17) and the patients with schizophrenia (n=18), with the Talairach coordinates and p value for the local p minimum for each cluster. There were no loci that showed significantly greater activation for the AL condition, relative to SR. Loci which showed significantly more activation in the controls compared with the patients and those that showed more activation in the patients compared to the controls are also listed.
AL, affect labeling; BA, Brodmann area; L, left; R, right; RSC, retrosplenial cortex; SR, self-reflection; Tal, Talairach coordinates.
