[Electrophysiologic evidence of three different types of the 'slow fibers' of extraocular muscles (author's transl)].
The author reports on electrophysiologic investigations of extraocular muscles in rabbits in vivo by means of standardized glass microelectrodes. The results of investigation on muscle-fiber membrane resting potentials of 'slow fibers' as well as on postsynaptical potentials of 'slow fibers' are analyzed after having elucidated the problems as well as the methods employed and the experimental setup. By figures and synopses in tabular form the author illustrates the electrophysiologic parameters of three different types of muscle fibers of 'slow fibers' of extraocular muscles that can with certainty be differentiated electrophysiologically. In the discussion references are made to the importance of the submitted results of investigation for basic research and for clinical ophthalmo-electromyography. Finally, the trends of investigation of the electrophysiologic analysis of extraocular muscles are discussed.
