[Animal experimental investigations of the electrophysiologic parameters of 'fast fibers' of extraocular muscles by means of glass microelectrodes (author's transl)].

The author reports on animal experimental investigations of the electrophysiologic parameters of 'fast fibers' of extraocular muscles in rabbits in vivo by means of standardized glass microelectrode. The submitted results of investigation enlarge our knowledge of the electrophysiologic parameters of 'fast fibers'. The statistically analyzed results on musclefiber action potential parameters, on musclefiber membrane resting potentials, strengthduration curves and the data on the electro-mechanical latency period of 'fast fibers' are illustrated by figures. The most important conclusions for basic research on 'fast fibers', for clinical ophthalmo-electromyography and for the duality concept of eyemovement control are given.
