Figure 2. Movement-related potentials (MRPs) were affected by the predictability of the imperative release cue.

Figure 2

A. Grand average movement-related potentials derived from control trials at each of the nine EEG electrodes for both the PREDICT (black) and REACT (red) conditions. The cartoon to the right shows the locations of the electrodes on the scalp. B. Average integrated EEG calculated over 100 ms time bins at 8 time points centered on −4500, −2500, −1500, −1000, −500, −250, −100, 0 ms. Differences between conditions were significant (p<0.007) at all time points except at baseline (−4500 ms). C. Average slope of the movement-related potentials over three time intervals. The slopes were significantly different between conditions during movement preparation but not baseline (PRE) (p<0.007).
