Values in parenthesis mean the number of subjects. SI/MI, primary sensorimotor area. In SI/MI in contralateral side, the number of dipole sources is the sum of MF, MEFI, MEFII, and MEFIII components. 3b, area 3b. Note sources specified in area 3b were cited independently from areas involved in SI/MI. SII, secondary somatosensory area. In SII, for both movement and stimulation data, the same subjects showed one to three EDSs in both hemispheres. PPC, posterior parietal cortex; PM, premotor area; TPJ, temporoparietal junction; STS, superior temporal sulcus; SFG, superior frontal gyrus; SMA, supplementary motor cortex; ACC, anterior cingulate cortex; PC, precuneus; SC, striate cortex (visual area 1); ESC, extrastriate cortex.
Dipole source is located in the mesial portion of the cortex.
