Pre- and postoperative DCNN tract classification in patients with structural lesions, A. tumor and B. cortical dysplasia. While postoperative DCNN tracts of A showed no volume change in C1 and slight volume change in C9 causing normal face motor and mild language deficit after surgery, postoperative DCNN classes, C1,3 of B indicated significantly reduced or removed volumes following resection. This resection resulted in severe postoperative motor deficits on right face and hand motor functions.
