[Dynamics of neurophysiological indices in experimental animals with chronic circulatory vertebrobasillar disorders and chronic lumbosacral myeloid ischemia in response to magnetic fields and electric stimulation].

Three series of experiments were made on mature non-inbred male and females rats with body mass 160-200 g. Chronic circulatory vertebrobasilar disorder (CCVD) in the rats was provoked by ligation of subclavian arteries. The animals showed longer latent periods of evoked total motor potentials reflecting impairment of the central motoneuron. Inhibition of impulse conduction along the peripheral nerves and decreased M-response amplitudes in the experimental animals with CCVD and myeloid ischemia in the lumbosacral area points to a significant affection of the segmental system of the spinal cord and other parts of the autonomic nervous system.
