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.
Clay tablets are usually associated with cuneiform writing, a script that takes its modern name from the wedge-shaped (from Latin cuneus, "wedge") marks made by the stylus in clay.
A preliminary study found that binge drinking adolescents had greater activation in the SFG, superior parietal lobule, inferior parietal lobule (IPL), and the cingulate, as well as lower activation in one cluster encompassing the cuneus, precuneus, lingual gyrus, and parahippocampal gyrus (PHG) during novel word encoding.
In our analyses, we consider gray-matter volumes of the total brain, the four lobes (frontal, parietal, temporal, occipital), the hippocampus, the deep-gray structures (thalamus, caudate, putamen, and pallidum), and total volume of multiple gray-matter regions known to atrophy preferentially in Alzheimer's disease (parahippocampal, entorhinal, and inferior parietal lobules, hippocampus, precuneus, and cuneus), which we refer to as the AD signature region (Dickerson et al.
Especially, left GP showed strong correlations with the right HIP and GPi, left CAU and NA, and bilateral frontal lobe, PCUN, SOG, MOG, Cuneus (CUN), MCG, PCG, INS, PUT, GPe, and STN, and right GP showed strong associations with the right SOG and GPi, left AG, and bilateral MOG, CUN, MCG, and STN.
For the Success event, SCZ + S patients also had decreased activations in the right medial frontal/anterior cingulate gyrus, cuneus, and cerebellar culmen and left middle occipital gyrus, in comparison to healthy men.
In HS, positive correlations between amplitude and neural activity were observed in the CAL, middle cingulate cortex (MCC), cuneus, fusiform gyrus, and insula, and negative correlations were observed in the anterior cingulate cortex (ACC), prefrontal cortex (PFC), and precentral gyrus (PreC).
The results show that the left frontal cluster (LFC) had significant differences among the three groups of subjects and the left temporal cluster (LTC) has a significant difference between BD and UD; the cuneus may provide neurological signs of depression in patients with BD and UD [25].
No significant difference in SUVR before and after light stimulation was seen (Prim = primary visual, Vis = visual association, Par = Parietal lobe, Cun = Cuneus, and Cing = posterior cingulate).
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.
Figure 7 shows the fiber orientations estimated from ODF fields constructed with QBI, CSA-QBI, and DOT in the ROI region through which cuneus fibers, vertical occipital fasciculi, and superior longitudinal fasciculi pass.
Cuneus area as a part of visual network was observed to be more activated for the karate players when compared with the control subjects.
