The present study demonstrates the utility of examining extracted resting state information in the context of cognitive and network architecture sequelae in schizophrenia. We examined the whole-brain correlation with Broca's and Wernicke's area BOLD signals in individual schizophrenic (SZ) patients, normative (NC) subjects, and subjects at high genetic risk (HR) for SZ. HR subjects were found to exhibit more diffuse connectivities with the two language areas than either SZ or NC subjects. Moreover, SZ and HR subjects exhibited substantial hyperconnectivity between the cerebellum and language areas. The wider implications of examining the extracted resting state BOLD signal is also discussed.
