[Effect of alcohol on interhemispheric functional relations in patients with late sequelae of cranio-cerebral injuries].
Using the backward masking method the time of perception of visual stimuli in the right and the left field of vision was examined. It was found that in patients with craniocerebral injury sequelae, as well as in healthy subjects the time of perception of literal stimuli was shorter in the left field of vision, i.e. the information entering the right hemisphere was processed more rapidly. Under the action of alcohol the asymmetry of the perception time disappeared in the patients, and became inverse in the healthy subjects, i.e. the time of perceiving letters in the left field of vision got longer than in the right field. Under the action the right hemisphere seemed to lose its advantage in the speed of the stimuli perception. It is supposed that the right hemisphere is more sensitive to alcohol.
