With a Z-score of -0.55 (29.0th percentile), this represents normal volume ; hippocampal volume measures 7,691 mm³, 0.1% above the reference mean. With a Z-score of 0.01 (50.4th percentile), this represents normal volume ; whole brain volume measures 1,002,320 mm³, 2.6% below the reference mean. With a Z-score of -0.32 (37.3th percentile), this represents normal volume ; entorhinal cortex volume measures 4,050 mm³, 4.0% above the reference mean. With a Z-score of 0.31 (62.3th percentile), this represents normal volume ; fusiform gyrus volume measures 17,071 mm³, 6.3% below the reference mean. With a Z-score of -0.70 (24.1th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,309 mm³, 1.0% below the reference mean.
