Mapping of cingulate motor function by cortical stimulation Volume 15, numéro 3, September 2013



Figure 1 Location of depth electrodes and corresponding clinical response at each contact electrode. Lateral view of skull x-ray showing placement of four depth electrodes, arbitrarily referred to as “AD, BD, DD, and ED”, each with 8 to 10 contacts (AD1-8, BD1-8, DD1-10, and ED 1-8, respectively). Stimulation of ED2 resulted in right arm motor activity and stimulation of ED3 resulted in right leg motor activity, shown in the inset ( upper right extremity motor activity; lower right extremity motor activity).



Figure 2 Co-registered MRI and CT images. A) Axial and B) coronal views of ED3 electrode contact on ventral bank of cingulate sulcus (arrow); C) axial and D) coronal views of ED2 electrode contact on dorsal bank of cingulate sulcus.
