lying a low-pass anti-aliasing filter with a cutoff frequency of 40 Hz and then downsampling by a factor of 10. A zero-phase, fourth-order, low-pass Butterworth filter with a cutoff frequency of 1 Hz was then applied to the kinematic and EEG data. The cutoff frequency was determined experimentally with infl

sa of the right eye for vertical eye movements and to the external canthi for horizontal eye movements. Hand position was sampled at 100 Hz using an Optotrak motion sensing system (Northern Digital, Inc) that tracked an infrared LED secured to the fingertip with double-sided adhesive tape.

Signals from each EEG electrode were decimated by a 149 factor of 5 (to 100 liz), then filtered with a zero-phase, 3rd order, band-pass Butterworth filter 150 (0.1 — 2 Hz) and normalized by subtracting their mean and dividing by their standard deviation 151 (Bradbeny et al. 2010).
