Figure 5

Activation of median nerve stimulation detected with CCA, CCA + CA, CCA + MSC. Significance levels were controlled at p = 0.01 for all images. Z thresholds were changed for each technique based on the significance level. A: CCA, Z = 4.8, FWHM = 4 mm B: CCA + CA, Z = 2.6, cluster size threshold = 6 voxels, FWHM = 4 mm C: CCA + MSC, Z = 2, kernel size = 0.05, FWHM = 4 mm D: CCA + MSC, Z = 2, kernel size = 0.10, FWHM = 4 mm E: CCA + MSC, Z = 2, kernel size = 0.15, FWHM = 4 mm F: CCA + MSC, Z = 2, kernel size = 0.20, FWHM = 4 mm G: CCA, Z = 4.8, no filter applied H: CCA + CA, Z = 2.6, cluster size threshold = 4 voxels, no filter applied I: CCA + MSC, Z = 2, kernel size = 0.05, no filter applied J: CCA + MSC, Z = 2, kernel size = 0.10, no filter applied K: CCA + MSC, Z = 2, kernel size = 0.15, no filter applied L: CCA + MSC, Z = 2, kernel size = 0.20, no filter applied.
