<P> Fujiwara et al. (2007) did an experiment in which they correlated the size of anterior cingulate gyrus in people with schizophrenia with their functioning on social cognition, psychopathology and emotions with control group . The smaller the size of anterior cingulate gyrus, the lower was the level of social functioning and the higher was the psychopathology in the people with schizophrenia . The anterior cingulate gyrus was found to be bilaterally smaller in people with schizophrenia as compared with control group . No difference in IQ tests and basic visuoperceptual ability with facial stimuli was found between people with schizophrenia and the control . </P> <P> People with schizophrenia have differences in the anterior cingulate gyrus when compared with controls . The anterior cingulate gyrus was found to be smaller in people with schizophrenia . The volume of the gray matter in the anterior cingulate gyrus was found to be lower in people with schizophrenia . Healthy females have larger rostral anterior cingulate gyrus than males, this sex difference in size is absent in people with schizophrenia . The metabolic rate of glucose was lower in the left anterior cingulate gyrus and in the right posterior cingulate gyrus . </P> <P> In addition to changes in the cingulate cortex more brain structures show changes in people with schizophrenia as compared to controls . The hippocampus in people with schizophrenia was found to be smaller in size when compared with controls of the same age group, and, similarly, the caudate and putamen were found to be smaller in volume in a longitudinal study of people with schizophrenia . While the volume of gray matter is smaller, the size of the lateral and third ventricles is larger in people with schizophrenia . </P> <Table> <Tr> <Td> </Td> <Td> This article's tone or style may not reflect the encyclopedic tone used on Wikipedia .

The cingulate cortex is a subcortical structure above the corpus callosum
