IPS region in the response inhibition network. A, Parcellated areas that were conjunctively positive in brain activation (Fig. 3B), connectivity with the IFC (Fig. 3C, top), and connectivity with the preSMA (Fig. 3C, bottom). RSFC, Resting-state functional connectivity. B, A group-level probability map of locations of positive regions that were activated during response inhibition and connected with the IFC and preSMA. C, A map of target IPS regions in 12 individual subjects. There are therefore 12 points in the map, but some of them are overlapped. D, The magnitude of brain activation during response inhibition in the IPS and TPJ. Error bars indicate the SEMs of subjects. ***p < 0.005, t test. E, The connectivity between the IPS/TPJ and the IFC/preSMA. F, The PPC modules (left) and submodules (right) reported in the study by Nelson et al. (2010) are shown. Spheres in the brain surface represent ROIs in the study by Nelson et al. (2010). Different colors in the spheres indicate different modules/submodules. A red cross represents the center of the group probabilistic map in B. The identified IPS region in the present study corresponded to the IPS module, and also to the RIPS/dlPFC submodule. SPL, superior parietal lobule; SMG, supramarginal gyrus; FEF, frontal eye field; sFG, superior frontal gyrus; a, anterior, p, posterior; m, medial.
