Cortical activation during pressure stimulation. GLM analysis revealed significantly activated clusters in the insula, postcentral gyrus, rolandic operculum, supramarginal gyrus, precentral gyrus, median cingulate, and paracentral lobule (group analysis with 21 participants, F-test, p_(FWE) < 0.05, k > 5, bar: F-statistics, A: sagittal view, B: coronal view, C: transverse view). The left side at B and the upper side at C indicate the contralateral hemisphere (contra.); the right side at B and the bottom side at C indicate the ipsilateral hemisphere (ipsi.); and activation at A indicates all suprathreshold voxels from both the contralateral and ipsilateral hemispheres.
