In addition, seven gross subcortical ROIs were rated: the anterior cingulate gyrus (BAs 25, 32, 33, and the anterior aspect of BA 24); the left and right insula; the left and right caudate nuclei; and the left and right putamens.
The two comparison group concentration decreases were in the left caudate and right putamen.
