Maps and histogram for the paired -test between PSGS and NO PSGS. (a) and (b) indicate the paired -test map for PSGS < NO PSGS in the acupuncture and tactile runs, respectively. Two thresholds were selected and overlapped on the map: , uncorrected (colored in blue), and , uncorrected (colored in green) with 5 contiguous voxels, respectively. (c) shows the histogram of the paired -test between PSGS and NO PSGS. The red line represents the acupuncture run, and the blue line indicates the tactile run. , uncorrected, and , uncorrected, are marked on the histogram.
