a Relationship of the threshold measurements in anodic (CAC, red circles) and cathodic (ACA, blue squares) stimulation mode between the two adaptive tracks performed by all subjects. Thresholds were normalized per subject by subtracting the average threshold across electrodes from each measurement. b Relationship of the PE calculated separately for the two adaptive tracks
