Starting from a general description of the several components which form movementrelated cortical potentials family, this paper aims to review the principal results coming from electrophysiological and motor neuroscience experiments. Empirical evidences of cortical and subcortical generators are analyzed, considering their mutual and simultaneous involvement for the generation of Bereitschaftspotential (BP) or Readiness Potential (RP). A specific section is dedicated to the review of the main psychological factors which influence the topography and magnitude of BP. Inside this psychological perspective another section deals with the role of motor representation for the preparation of the action, valuating the influence of motor imagery process on readiness potential.
