Localization of active cortical areas for overt (A and C) and imagined (B and D) movements. Minimum current estimation (MCE) was used to localize active cortical sources during the time period used for decoding analysis in subject S1. Data were averaged over all repetitions for leftward movement. A and C: cortical activity from −200 to 0 ms relative to the onset of overt movement. B and D: cortical activity from 300 to 420 ms relative to target onset for imagined movement. The contralateral motor cortical area shows strong activation. In addition, there is a certain degree of visual and ipsilateral motor cortical activity.
