Figure 1.

Illustration of analysis steps and temporal variability of dALFF pattern. (A) The pre-processed full-length BOLD fMRI time series was segmented into several sliding windows (50TRs). The temporal variability of the dALFF was defined as the variance of dALFF maps across the sliding windows. The pattern of temporal variability of the dALFF in the DR group (B) and HC group (C). The different temporal variability of dALFF between two groups. (D) dALFF, dynamic amplitude of low-frequency fluctuation; DR, Diabetic Retinopathy; HC, Health Controls.
