Influence of the duration of previous foreperiod (FPn−1) on saccadic latency during the current foreperiod (FPn) in the different groups of subjects. The influence of the previous foreperiod was significant only in controls (A) and Parkin patients (B) but not in iPD patients (C, ON1-OFF2 group; D, OFF1-ON2). See text for statistics.
