Abstract

Injection of a sublethal dose of botulinus toxin into one masseter muscle leads to unilateral paralysis of that muscle, accompanied by the development of biting. Membrane polarization and the amplitude of the action potential mainly of highly polarized muscle fibers are depressed in the paralyzed region, but the function of fibers with a low level of polarization is only slightly affected.
