This table reports the relocation of activation peak coordinates from first to second MEG scan for the 75 patients with activation peaks within the motor cortex; 75 patients presented for two MEG-based motor mappings, and 11 patients from the first group presented for a thirs MEG-based motor mapping subsequently. We report the respective interclass correlation coefficient scores for motor peak head coordinates. Abbreviations: SD, standard deviation; min, minimum value; max, maximum value; ICC, interclass correlation coefficient; Sig., significance value; n, number of patients.
