FIGURE 2

Behavioral performance, directional EMG activity, and readiness potential. (a) Grand average (n = 34) of accuracy of choices per stimulus strength. (b) Grand average of decision time per stimulus strength. (c) Grand average EMG response for the biceps when reaching for the flexion versus extension target. (d) Grand average EMG response for the triceps when reaching for the flexion versus the extension target. (e) Grand average preparatory activity (i.e., readiness potential) over the Cz electrode prior to reach onset. Shaded areas in all panels indicate S.E.M.
