Fig. 2From: Differences in brain activity between normal and diabetic rats under isoflurane anesthesia: a resting-state functional MRI studyPower spectral density (PSD) in different brain regions between control and diabetes groups. The shaded regions indicate the frequency range (0.01–0.1 Hz) for calculating fractional amplitude of low-frequency fluctuation.
