[Motor phenomena during electric stimulation of the brains of epileptics].
Ninety-eight patients with long-term electrodes implanted into different structures of the brain were subjected to clinical and electrophysiological examinations. Motor phenomena activated by electrical stimulation of the brain were studied by radiotelemetry and stimulation myography. The threshold and amplitude of H-reflex was shown to be decreased during the interictal period. In cases of the development of a non-convulsive attack, there was a bilateral elevation in the value of the monosynaptic potential. This indicator reached the peak value before the appearance of bilateral tonicoclonic convulsions. The authors note that the clinical characteristics of the activated epileptic phenomena depend not only on the site of electrical stimulation but also on the direction of the after-action discharge propagation.
