Finger tap errors as a function of target tap combination. Each line shows the occurrence of error taps during multi finger tapping. Error occurrence is given for each finger in % (mean ± SD) of target taps in the relevant condition for patients (left) and in control subjects (right). Example: in 10 % of all one-finger target taps with the index finger (target digit 2), patients also tapped erroneously with the little finger (digit 5). The first four lines describe each one-finger target tap condition, the following six lines every two-finger target tap combination. “Xs” indicate coincidence of target finger(s) and correct tap finger(s). Color scale indicates the level of error: white = no error (0 %), red > 60 % errors
