We found that ReHo in the right caudate and inferior temporal gyrus was higher in both schizophrenic patient groups than in the healthy controls whereas ReHo in the bilateral postcentral gyrus and thalamus and the right inferior occipital gyrus was lower in both schizophrenic patient groups (FDR corrected, P < 0.
In our study, Joint-Source 15 from the SBM analysis showed differences in the brains of schizophrenic and healthy volunteers in the middle frontal gyrus, precentral gyrus, subgyrus, postcentral gyrus, superior frontal gyrus, medial frontal gyrus, cingulate gyrus, and superior temporal gyrus.
Speaking: Areas of activation were observed bilaterally in the superior frontal gyrus (BA6), and the insula (BA13) and the inferior parietal lobule (BA47), the superior parietal lobule (BA7), the superior temporal gyrus (BA22) and the postcentral gyrus (BA43) of the left hemisphere, the superior temporal gyrus (BA 42, 38) and the precentral gyrus (BA6) of the right hemisphere.
Results: The main areas with increased brain activation were in frontal and parietal lobe, including left medial frontal gyrus, left inferior frontal gyrus, right middle frontal gyrus, right postcentral gyrus, and inferior parietal lobule in patients after CRT, yet no decreased brain activation was found.
55] More recently, researchers used the amplitude of low frequency fluctuations (ALFF) to evaluate resting-state brain functions and found that among individuals with schizophrenia the ALFF was elevated in the right corpus callosum, occipital lobes, left cerebellar lobe, superior frontal gyrus and precuneus, and the ALFF was decreased in the bilateral postcentral gyrus and left precuneus.
Their score on the Beck Depression Inventory also improved in correlation with decreased activation in the superior frontal gyrus and postcentral gyrus.
Compared to the baseline in the 2 years follow-up, the patients with PD presented with increased fALFF values in the right middle temporal gyrus and right middle occipital gyrus while also having decreased fALFF values in the right cerebellum, right thalamus, right striatum, left superior parietal lobule, left IPL, left precentral gyrus, and left postcentral gyrus (P < 0.
