Abstract
Examination of functional asymmetry of the cerebral hemispheres by dichotic auscultation in 83 patients (aged 12-19 years) with infantile cerebral paralysis and 228 normal subjects showed left-side dominance in 76\% (right ear coefficient REC = +22.01) of patients with spastic diplegia (n = 45) and in 76\% (REC = +26.0) of normal subjects; in cases of left-side hemispheres (n = 13) this parameter was 100\% (REC = +35.5) and in right-side hemiparetic form 60\% (REC = +22.8). The findings confirm a genetic nature of functional asymmetry of the cerebral hemispheres and indicate a high degree of cerebral hemisphere dominance.
