By intracellular leading off of potentials a study was made of an electrophysiological characteristics of the fibers of the eyebrow-auricular muscle in rabbits anesthetized with urethane. The muscle fibers were stimulated by current impacts, 5 msec in duration with the frequency of 5 pulse/sec. Membrane rest potentials, amplitudes of action potentials, duration of action potentials and latent periods had mean values typical of the muscle fibers of phasic type. A conclusion was drawn that the fibers of the muscle under study were homogenous and belonged to the phasic type.
