Notes: Results were corrected by AlphaSim(all the clusters survived p < 0.05, a combined threshold of p < 0.01 with a minimum cluster sizes of 116,115,162,150,79 and 157 voxels, respectively ).The coordinates were showed in the Montreal Neurological Institute (MNI) standard space. PNES, psychogenic non-epileptic seizures; Hem, hemisphere; BA, Brodmann area; L, left; R, right.
