Back in 1964, two movement-related cortical potentials, the so-called Bereitschaftspotential (readiness potential) and the contingent negative variation were coincidentally described by two independent groups of investigators. Both of these evoked potentials reflect dynamic changes in motor cortical activity 11.5 s prior to movements, and thus mirror the preparation and/or anticipation of movement. But whereas the Bereitschaftspotential appears with self-paced, voluntary movements, the contingent negative variation is related to cued movements. Over the following years and decades, other EEG measures of premovement-related processes, such as the
