[The action of ionizing radiation on the central nervous system (based on clinical and polymodal evoked potential data)].

A clinical examination was done as was an investigation into polymodal evoked potentials (EP) of the brain in the group of 123 liquidators of the accident (LA) to the N 4 reactor unit of the Chernobyl nuclear power station. There was a steady decrease in the amplitude of auditory EP of the brain stem (AEPBS), somatosensory EP, visual EP and a great lengthening of latent periods (LP) of late cortical components H200, II300, H400. LP AEPBS appeared to be intact in 91.

[Cerebral hemodynamics in the acute and remote periods of closed cranio-cerebral trauma].

By using clinical and zonal REG methods the authors examined 204 patients with brain traumas. Such examinations permitted to detect symptoms of a disturbed cerebral vascular tone. In the acute period of a closed brain trauma changes of cerebral hemodynamics were not stable and were nonhomogenous by direction.
