It was also found in this study that, compared with the normal group, ReHo value of aMCI patients increased and concentrated mainly in the right frontal lobe, left fusiform gyrus, inferior frontal gyrus, superior temporal gyrus, and right thalamus.
After the speech, the inferior frontal and middle temporal gyrus in the left hemisphere and the left cuneus the right precuneus and supramarginal turn in both hemispheres were activated.
Li and colleagues found that there was improvement in the left superior temporal gyrus function and enhancement of the functional connectivity from the left STG to the dorsalateral prefrontal cortex(DLPFC) in patients with first-episode schizophrenia(FES) after taking atypical antipsychotic drugs (olanzapine, clozapine, aripiprazole, risperidone, quetiapine, or amisulpride) for a year and these changes were correlated with the improvement of negative symptoms.
A longitudinal investigation found that binge drinking adolescents, compared with control subjects, had lower activation in the IFG, IPL, miTG, and superior temporal gyrus across time, suggesting a different pattern of brain activation that occurs prior to binge drinking and persists after alcohol initiation.
We suggest that GMV reduction in superior temporal gyrus and WM impairment in the forceps minor may play a key role in chronic schizophrenia patients with moderate-to-severe depressive symptoms.

Images show a similar decrease in the radioactive pattern, such as for the right superior temporal gyrus (red arrow, x = -50, y = -4, z = 5) and posterior cingulate cortex (blue arrow, x = 2, y = -41, z = 23).
Significant volume reduction in converters was also observed in the precentral gyrus, superior frontal gyrus, middle temporal gyrus, and nucleus accumbens at the first two visits.
Our results indicated increased GM volume in the bilateral auditory network (superior temporal gyrus), mainly overlapped with AAC.
In contrast to Examples 2 and 3, tau pathology confirms abundant neurofibrillary tangle pathology, including within anterior cingulate cortex (G), temporal neocortex of middle temporal gyrus (H), and primary visual area (I).
In the Seed-to-Voxel analysis, right frontal pole, right middle temporal gyrus, and left superior frontal gyrus were less correlated with the PCC in patients compared to controls (Figures 7 and 8).
Significantly negative correlations were found between YBOCS scores and left superior parietal lobe gray matter r(28)= -.68, p<.001, right angular gyrus white matter r(28)= -.60, p<.001, and right superior temporal gyrus white matter volumes r(28)= -.61, p<.001.
