Corpus callosum function in schizophrenia: a neuropsychological assessment of interhemispheric information processing.

Impaired corpus callosum function has been reported in schizophrenia. We measured intra- and interhemispheric visual information processing in 16 schizophrenic patients and 16 matched controls. Although the schizophrenics performed worse between than within cerebral hemispheres, this pattern was similar to that of the normal controls. Schizophrenics do not show particular dysfunction of the corpus callosum.
