Between Group Differences in Amplitude of LFO w/o (A) & with (B) Correcting GM Volume

Between-group differences in the amplitude of LFO without (A) and with (B) correcting GM volume.

The svMCI patients showed decreased LFO amplitudes in frontal and temporal regions whereas increased LFO amplitudes in parietal and occipital regions. Of note, the between-group differences in the LFO amplitudes exhibited highly similar patterns between with and without correcting GM volume. 

The statistical threshold was set at P<0.01 for individual voxels and cluster size >972 mm3, which corresponded to a corrected P<0.01 determined by Monte Carlo simulations.
