With a Z-score of 0.71 (76.1th percentile), this represents normal volume ; hippocampal volume measures 7,954 mm³, 3.5% above the reference mean. With a Z-score of 0.39 (65.3th percentile), this represents normal volume ; whole brain volume measures 1,001,660 mm³, 2.7% below the reference mean. With a Z-score of -0.33 (37.0th percentile), this represents normal volume . ",
