Hemispheric dominance in schizophrenics as determined on extrapyramidal side effects of neuroleptics

Phenomena observed during treatment with neuroleptics were clinically measured in an attempt to determine the difference in vulnerability of the two hemispheres and the relation between this difference and schizophrenic diseases. In the group of systematic schizophrenias the increase in tonus was significantly higher in the dominant hemisphere. This finding is considered a verification of the nosological hypothesis of schizophrenias.
