Receiver operator curve analyses for the three pathways, C1: mouth/lip (▴), C2: finger (♦), and C3: leg (▪). For each of five separation criteria (contact, 5 mm, 10 mm, 15 mm, 20 mm), the group average of sensitivity, specificity, and accuracy was evaluated from epilepsy children without lesion (left column, n=16) and with lesion (right column, n=15).
