title: [The diagnostic significance of electrophysiological analysis of orientation reflex in hemispheric ischemic stroke].
abstract: Diagnostic significance of orientation reflex in response to neutral sound stimuli in hemispheric ischemic cerebral stroke is discussed. The following electrophysiological indices for orientation reflex were analysed: desynchronization reaction, non-specific vertex EEG potential and spontaneous electrodermographic activity--galvanic skin reflex to repeated sudden neutral audio stimuli were analysed. Beginning from the acute period of stroke, a follow-up study was carried out. Correlations between stroke severity and orientation reflex stability as well as between a rate of some pattern diminution in the early rehabilitation period and hemispheric lateralization of the pathological focus and severity degree of the neurological deficit were found.
