Right supramarginal gyrus is crucial to overcome emotional egocentricitty bias in social judgments.
After intervention, the activation is in the temporal gyrus, precuneus and the supramarginal gyrus of the right hemisphere (See Figure 3).
TEI/TEE = tail end of inspiration/expiration; fALFF = fractional amplitude of low frequency fluctuation; ReHo = regional homogeneity; DC = degree centrality; NS-r/HS-r = correlation coefficient in normal/hypnosis state; L/R/B = left/right/bilateral; LG = lingual gyrus; PCu = precuneus; CAL/CPL = cerebellum anterior/ posterior lobe; ACC/MCC/PCC = anterior/middle/posterior cingulate cortex; MPFC/PFC = (medial) prefrontal cortex; SFG/MFG/IFG = superior/ middle/inferior frontal gyrus; PreC/PostC = precentral/postcentral gyrus; SMA = supplementary motor area; SMG = supramarginal gyrus; IPL = inferior parietal lobule; Put = putamen; fusiform = fusiform gyrus.
Specifically, MDD patients displayed a significantly decreased global efficiency of the right rolandic operculum, the right supramarginal gyrus, the right angular gyrus, the right Heschl's gyrus and the left middle temporal gyrus (temporal pole).
When looking at the comparison between HC and DD groups, we found that HC did not show any-increased activations relative to DD, while DD presented significantly more activations in the right supramarginal gyrus (MNI coordinates: x = 63; y = -38; z = 24; 37 voxels; z = 3.55; P = 0.025).
Psychomotor areas of the cerebral cortex is planning and is programming the movement by planning the ideation plan of motric action in Brodmann area 40 (supramarginal gyrus) being transmitted in psychomotor centers which construct the movement engrams (Brodmann areas 6(3 and 8) and, finally, is being transferred to cerebral hemispheres motor areas of the same or opposite cerebral hemisphere through the corpus callosum.
In the first examination, tennis imagery elicited a larger activation than SN in the left and right inferior parietal lobe (IPL), the secondary somatosensory cortex (Brodmann area (BA) 40), the left supramarginal gyrus, and the middle frontal gyri (BA8, BA10).
The supramarginal gyrus (SM) is therefore, longer than it is tall and the angular gyrus (ANG) is more posterior and inferior.
Previous research reported an increased rs-FC between the right supramarginal gyrus and right precentral gyrus after an initial 2 weeks of training, but found a decreased rs-FC in the last two weeks when the behavioral performance started to improve and stabilize [43].
The research team headed by Tania Singer from the Max Planck Institute for Human Cognitive and Brain Sciences has discovered that when the right supramarginal gyrus doesn't function properly or when we have to make particularly quick decisions, our empathy is severely limited.
Using surface based morphometry (SBM), Fan and Colleagues [6] found that individuals with OCD had greater cortex thickness in the right inferior parietal region and increased gyrification indices in the left insula, left middle frontal gyrus, left lateral occipital region extending to the precuneus, and in the right supramarginal gyrus. They also found a positive correlation between the YaleBrown Obsessive-Compulsive Scale (YBOCS) score and the local gyrification index of the left insular lobe.
