Abstract

Reduced functional connectivity (FC) in schizophrenia has been demonstrated either in task related or 'default network' areas, but not between these networks, which interact meaningfully. We examined the role of FC between the inferior frontal gyrus (IFG) and medial prefrontal cortex (mPFC) in determining language-lateralization during a language task, and its association with structural integrity of the corpus-callosum. Only schizophrenia patients presented increased mPFC-IFG FC during task, which additionally corresponded to decreased white-matter organization of the corpus-callosum. These findings suggest that inability to suppress irrelevant internally-generated information while processing external stimuli might be the basis of functional psychopathology in schizophrenia.
