With a Z-score of -0.49 (31.1th percentile), this represents normal volume ; hippocampal volume measures 6,245 mm³, 3.8% below the reference mean. With a Z-score of -0.31 (37.9th percentile), this represents normal volume ; whole brain volume measures 926,449 mm³, 0.2% below the reference mean. With a Z-score of -0.02 (49.1th percentile), this represents normal volume ; entorhinal cortex volume measures 3,590 mm³, 3.7% above the reference mean. With a Z-score of 0.20 (57.9th percentile), this represents normal volume ; fusiform gyrus volume measures 16,913 mm³, 5.0% above the reference mean. With a Z-score of 0.37 (64.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 19,480 mm³, 8.0% above the reference mean.
