Over the last decades the developments and applications of electromyo- graphic and electroneurographic methods have been of great value in giv- ing us insights into the functions of various neuronal systems. More re- cently, considerable advances in new technologies, e.g. computerization and microtechniques, as well as a remarkable increase of interest in the functions of the central nervous system, especially in motor control, can be recognized. The tremendous advances in the development of electromyography, electroneurography and evoked potential recording as well as in record- ing of...
