2) Hoffman auditory hallucination score was negatively correlated with the DC of the bilateral putamen, but positively correlated with the DC of the left superior frontal gyrus in patient with AH group [Figure 2].
The decreased putamen DC value and increased left superior frontal gyrus DC value in all patients and the relationship between symptoms and DC value are the best evidence.
The significantly decreased putamen DC value and increased left superior frontal gyrus DC value in APG reveal that schizophrenia with AH has decreased position of the bilateral putamen and increased position of left superior frontal gyrus in the whole-brain networks.
Li and colleagues found higher FA and AD in the truncus and genu of the corpus callosum and in the right superior frontal gyrus among individuals with OCD, but did not find any differences in the RD; furthermore, the FA value in the left middle temporal lobe was positively correlated with the severity of OCD symptoms.
19] In a subsequent study, [21] the same research team assessed a sample of patients with intractable OCD and found increased glucose metabolism in several brain regions: left cingulate gyrus, gray matter in the superior frontal gyrus, gray and white matter in the middle frontal gyrus, white matter in the inferior frontal gyrus, white matter outside the putamen, white matter in the anterior commissure of the limbic lobe, parahippocampal gyrus, dorsomedial nucleus of the thalamus, and amygdale.
Compared with the nonaerobic group, fMRI testing showed that subjects in the cardiovascular training group had significantly greater activity in the medial frontal gyrus, the superior frontal gyrus, and the inferior parietal lobule, and significantly lower activity in the anterior cingulate cortex.
