Methods: All rats were anesthetized and scanned in axial, sagittal, and coronal positions with a 7.0 T MRI. The signals of N-acetylaspartate (NAA), choline-containing compounds (CHO), glutamate (GLU), and myo-inositol (MI) were determined by PRESS sequence acquisition 1H spectra in the hippocampus and prefrontal cortex. After scanning, the target antigen was detected by immunohis- tochemistry (IHC). Results: The sucrose consumption in the model group was significantly decreased compared with the control group (P<0.05). The level and vertical scores of the model group in an open field experiment were significantly lower than the control group (P<0.05).
