Left panel shows statistical r-map for correlation of activity during working memory task to number of ADHD symptoms endorsed. Posterior cingulate cluster (circled) emerged as significantly correlated (cluster r = −0.865, max vox = [−9 −33 42], K = 245, corrected p-value = 0.002, and right panel shows the scatterplot of this relationship, displaying correlation of mean signal change in this cluster during working memory task to number of ADHD symptoms endorsed.
