DCS mapping. This surface view of the human cortex visualizes language-positive regions during intraoperative DCS language mapping using an object-naming task presented with the cortical parcellation system (CPS). Left column represents the first, the right column outlines the second awake surgery. Rows 1–3 represent patient 1–3. Dark areas = DCS positive CPS regions; black line = craniotomy limits.
