Fig. 4.
The intensity and number of voxels after versus before training. The horizontal axis illustrates the 1 − PFWE (corrected) value of a paired t test result, whereas the vertical axis shows the number of voxels with the corresponding P value. The difference between posttest versus pretest was significant, if the 1 − PFWE (corrected) value was larger than 0.95. The gray bar indicates the significance area. No significance was detected in both IBMT (solid line) and RT (dashed line) groups.
