From: Non cell-autonomous role of DCC in the guidance of the corticospinal tract at the midline
In healthy volunteers, unilateral stimulation of the hand area of the dominant primary motor cortex elicited only contralateral MEPs (A, blue line, right hand), whereas ipsilateral MEPs were observed in the DCC patients (B–D, red line, left hand). Depending on the patient, the ipsilateral MEPs were smaller (B) or larger (C) than the contralateral MEPs. In patient #6, stimulation of the dominant hemisphere elicited only ipsilateral MEPs (D).
