Compared with the normal elderlies, ReHo values decreased in aMCI patients in the left temporal lobe (middle temporal gyrus and inferior temporal gyrus), left parahippocampal gyrus, occipital lobe, lingual gyrus, precuneus, and other regions (P<0.05; Figure 3, Table 1), while ReHo values increased in the right side frontal lobe (inferior frontal gyrus), left superior temporal gyrus, precentral gyrus (frontal lobe), right thalamus, the left fusiform gyrus, and other regions (P<0.05; Figure 4, Table 2).
Participants' brain activation while correctly remembering names was significantly greater in four brain cortical regions (including the middle frontal gyrus, inferior temporal gryus, middle temporal gyrus, and fusiform gyrus) after exercise compared to after rest.
The recognition of bodies and faces depends on dedicated areas of the brain, centred on 'an area located in the fusiform gyrus' called 'the fusiform face area', damage to which leads to the development of 'prosopagnosia': an inability to perceive or recognise faces.
Founded an atrophy in the left inferior temporal orders, upper half, the fusiform gyrus and the anterior parahippocampal gyrus.
Significantly thinner cortical areas for dervishes subjects were found compared with the control group in the hubs of the default mode network, as well as in the motion perception and discrimination areas including the right dorsolateral prefrontal cortex (DLPFC), the right lingual gyrus and the left visual area 5 (V5)/middle temporal (MT) and the left fusiform gyrus.
This effect correlated with functional connectivity between the fusiform gyrus and ventromedial prefrontal cortex (visual and valuation areas).
It was found that the slopes were positively correlated with the right temporal gyrus (r=0.46), right middle temporal gyrus (r=0.60), left middle temporal gyrus (r=0.75), left inferior temporal gyrus (r=0.43) and left fusiform gyrus (r=0.48), and the correlation was statistically significant (with Alphasim correction) (see Table 5 and Figure 4).
As shown in Figure 1 and Table 2, the ReHo values were higher in depressed patients in the right superior temporal gyrus, right middle temporal gyrus, left inferior temporal gyrus, left middle temporal gyrus, right middle frontal gyrus, triangular part of the right inferior frontal gyrus, orbital part of the right inferior frontal gyrus, right superior occipital gyrus, right middle occipital gyrus, bilateral anterior cingulate, and paracingulate gyri, and values were reduced in the right fusiform gyrus, left middle occipital gyrus, left lingual gyrus, and left inferior parietal except for the supramarginal and angular gyri.
Furthermore, lateralized cortical decreases were observed in the right middle frontal gyrus, inferior frontal gyrus, precentral gyrus, superior temporal gyrus, thalamus, and putamen and in the left cuneus, precuneus, cingulate gyrus, fusiform gyrus, middle temporal gyrus, and medial frontal gyrus.
