Objective　To provide a linear measurement for the disease associated with the hippocampus morphological changes.　Methods　The area, the sagittal diameter, the transverse diameter of hippocampi, and the spacing of the temporal lobe uncus were observed on 31 specimens, as well the correlation of them was analyzed after standardized processing.　Results　There was a significant sex difference (P<0.01) for the HPF transverse diameter around standardization. Homogeneity test of variance process and standardized processing, with Pearson correlation analysis, showed the remarkable positive correlation between area and the sagittal diameter of HPF around standardized processing（P<0.01）, remarkable positive correlation between area and the transverse diameter of HPF (P<0.05）, and remarkable positive correlation between area and the spacing of the temporal lobe uncus（P<0.01).　Conclusions　The hippocampus diameter, the sagittal diameter, the hook spacing can be used as linear indexes for exploring of hippocampus morphological changes.
