Fig. 2From: Differences in fractional amplitude of low-frequency fluctuations (fALFF) and cognitive function between untreated major depressive disorder and schizophrenia with depressive mood patients(a) Variance analysis of the standardized z-values of fractional amplitude of low-frequency fluctuations (zfALFF) in the slow-4 frequency band comparing MDD, SZDM, and HC. Highlighted colors indicate significantly different regions, corrected using GRF (Voxel p < 0.001, Cluster P < 0.05). (b) Comparison of slow-4 frequency band fALFF changes between the SZDM and HC groups, corrected using GRF (Voxel p < 0.001, Cluster P < 0.05). Yellow and blue represent regions where SZDM patients have higher and lower activity compared to HC, respectivelyBack to article page
