We conducted voxel-wise regression on connection probability change (subtracting pre- from post-training connection probability maps) with strategy index per group and tested for significant differences between groups. Significance was determined using the TFCE method and corrected for multiple comparisons with FWER under random field theory for a = 0.05. Seed regions were selected from the AAL atlas and the clusters were labeled using the Atlas of the Human Brain (Mai et al., 1997). The MNI coordinates, the p value, and the t value of the peak voxel are shown. Positive (negative) t values indicate higher (lower) correlation coefficient for the training compared to the no-training control group.
