[Evoked potentials in experimental neuritis (neuropathies) of the trigeminal nerve].

On the basis of an analysis of evoked potentials (EPs) the authors have studied alterations in the bioelectrical activity in experimental trigeminal neurites (neuropathies). The results have shown that the most important electrophysiological signs of experimental trigeminal neurites is a decrease in the amplitude of the positive phase of the vertex potential. This appears to reflect a weakened conductivity function of the nerve due to its pathomorphological changes and a higher amplitude of the negative phase of evoked potentials indicating hyperactivation of the nonspecific system.
