Schizophrenia could result from failure of correct lateralization and lead to white matter misconnectivity. Previously, white matter alterations were described in the cerebellum, the visual system and in the corpus callosum. We investigated these regions using TBSS and evaluated potential changes in lateralization of the optic radiation and the superior cerebellar peduncle. A reduction of fractional anisotropy in the whole corpus callosum and the optic radiation and a decreased lateralization of the optic radiation and the superior cerebellar peduncles were observed. Our findings substantiate the concept that schizophrenia is a neurodevelopmental disorder which affects fiber connectivity and white matter lateralization.
