Results of TBSS analyses. A, Higher FA in the corpus callosum was associated with stronger leftward shifts in attention after stimulation over the left IPS. B, Higher FA in the corpus callosum was associated with stronger leftward shifts in attention after cTBS over the left IPS after controlling for the effect of handedness (continuous variable). All results are presented after correction for multiple comparisons (p < 0.05). Results are displayed on the FSL FA template in the standard MNI space with given X, Y, and Z coordinates. L, Left; R, right. Only parts of the TBSS skeleton where significant effects (p < 0.05) were found are shown. The colors depict p-values.
