However, sleep disturbance was associated with increased thickness in the right postcentral gyrus, pericalcarine, and pars opercularis, as well as increased volume of the hippocampus and amygdala.
Different from NS, in HS, positive correlations between ReHo/DC and TEI/TEE were observed in the CAL, supramarginal gyrus (SMG), PFC, and insula, while negative correlations were observed in the CPL, MCC, supplementary motor area (SMA), PreC, postcentral gyrus (PostC), fusiform gyrus, and thalamus (Table 3; Figure 5).
Weakened brain regions were mainly located in the occipital cortex, including the left calcarine sulcus (CAL.L), left middle occipital gyrus (MOG.L), parietal cortex left postcentral gyrus (PoCG.L), and right inferior parietal lobule (IPL.R).
More specifically, the electrodes were placed so that the first and the second (numbered 0 and 1 in Figure 2) lie on the motor cortex over the precentral gyrus, and the third and the fourth (numbered 2 and 3) lie on the somatosensory cortex over the postcentral gyrus and in the proximity of postcentral sulcus, respectively (Figure 2).
Increased intrinsic activity in postcentral gyrus, superior frontal gyrus, left inferior frontal gyrus, and cerebellum has been observed for elite karate players as summarized in Table 4.
Right CAU had strong positive correlations with the right postcentral gyrus (POST), anterior cingulate gyrus (ACG), hippocampus (HIP), and INS, left THA, and bilateral frontal lobe, angular gyrus (AG), supramarginal gyrus (SMG), occipital lobe, and PUT.
MRI was done 24 hours after the intervention showed evidence of acute ischemic changes involving the right anterior parietal lobe in the region of the right postcentral gyrus. On discharge, the patient's left-sided weakness and facial droop improved significantly.
According to fMRI analysis, the activation induced by HT7 stimulation was observed on the bilateral postcentral gyrus, inferior parietal lobule, inferior frontal gyrus, claustrum, insula, and anterior lobe of the cerebellum, as well as on the left posterior lobe of the cerebellum.
Results: Compared with the healthy control group, the two schizophrenia groups showed significantly increased ReHo in the right caudate and inferior temporal gyrus and decreased ReHo in the bilateral postcentral gyrus and thalamus and the right inferior occipital gyrus (false discovery rate corrected, P < 0.05).
The abnormalities in the left postcentral gyrus were found only in older maltreated individuals.
