As many as 43 patients aged 44 to 79 years with acute ischemic brain stroke of hemispheric (n = 30) and stem (n = 13) localization underwent clinical and neurophysiological examinations including noninvasive transcutaneous cortical pacing and investigation of short-latent somatosensory evoked brain potentials. This made it possible to exercise objective dynamic control over the motor and sensitive conductive brain systems. Certain common regularities were revealed in the functional reconstruction of motor (pyramid) and sensitive conductors in the acute period of brain stroke. Quantitative criteria for estimating the degree of the functional motor and sensitive defect were determined together with those for predicting its recovery.
