Figure 6. The mean dALFF values of altered cerebrum regions. Compared with HCs, the dALFF values of the following region 1 in DON patients was increased: MFG_R (BA 10, t = 4.9595), while the dALFF values of the following region 2 was decreased: PreC_R (t =-3.6307). Abbreviations: dALFF, dynamic amplitude of low-frequency fluctuation; HCs, healthy controls; DON, diabetic optic neuropathy; R, right; MFG, middle frontal gyrus; PreC, precuneus; BA, Brodmann's area.
