Figure 6. Differential stimulation of somatosensory brain circuits elicited by PUNS as indicated by BOLD contrast signals.

Figure 6

Psuedocolor fMRI images illustrating BOLD contrast signals (p<0.001; threshold 9 voxels) are shown for responses to PUNS-M (green LUT) and PUNS-T (red LUT) stimulation of the right index finger. Areas which were co-activated by both PUNS-M and PUNS-T are indicated by yellow voxels. Slice numbers shown in yellow text are based on MNI conventions. Anatomical areas activated are indicated by the following abbreviations: MTg  =  medial temporal gyrus; S1  =  primary somatosensory cortex; Op  =  parietal operculum; pIN  =  posterior insula; aIN  =  anterior insula; IFg  =  inferior frontal gyrus; Put  =  putamen; pMCC  =  posterior middle cingulate cortex; SMA  =  supplementary motor area; aMCC  =  anterior middle cingulate cortex; SMg  =  supramarginal gyrus.
