Abstract

This report presents data from studies of the diagnostic significance of an orientational reflex (OR) to indifferent sound stimuli in hemispheric ischemic stroke. The following electrophysiological measures of the orientational reflex were studied: the desynchronization reaction, the non-specific EEG vertex potential, and spontaneous electrodermographic activity (skin galvanic reactions, SGR) in response to presentation of repeated sudden indifferent sound stimuli. Studies were performed during the course of illness, starting with the acute period of stroke. The results obtained from these studies showed that the severity of stroke correlated with preservation of the OR while the rate of extinction of individual components in the early recovery period correlated with the hemispheric lateralization of the pathological focus and the severity of the neurological defect.
