[Cortical motor potential associated with voluntary termination of a movement].
The data are presented on potentials revealed by averaging buman EEG sections recorded during termination of a motor act. The potential consisted of two components: fast positivity and slow negative wave. The complex under study was named "final" or "relaxation" potential. The latency of the "final" potential and that of the muscle relaxation were linearily related. The potential was recorded only in cases when the relaxation of all muscles involved was necessary for a motor task solving at movement termination. If some groups of muscles relaxed and the other ones contracted the potential was not recorded.
