Notes: Results were corrected by AlphaSim(all the clusters survived p < 0.05, a combined threshold of p < 0.01 with a minimum cluster size of 75 voxels).The coordinates were showed in the Montreal Neurological Institute (MNI) standard space. fALFF, fractional amplitude of low-frequency fluctuations; PNES, psychogenic non-epileptic seizures; HC, health controls; BA, Brodmann area; L, left; R, right.
