Results of cortical stimulation mapping (CSM) and N1 responses grouped by CSM positive and negative pairs. (A) CSM results categorized for all SDEs implanted. Electrodes which consistently caused a deficit during stimulation are shown in red, those which caused a deficit when part of one stimulating pair, but not another (edge effects) are in blue, SDEs which only resulted in a motor effect are green, those that were stimulated but never caused a deficit are black and all SDEs which were not evaluated by CSM are white. (B) Representation of the N1 responses during CCEP stimulation at electrode pairs that were CSM positive (no. 2-6). (C) Distribution of N1 responses across CCEP stimulation pairs, which were negative (no. 7-9) or not tested (no. 1 and 10). Only those brain surface locations with >2 electrodes within 8 mm were included to avoid distortion of the results by outliers.
