With a Z-score of -0.88 (18.9th percentile), this represents normal volume ; hippocampal volume measures 6,959 mm³, 7.9% below the reference mean. With a Z-score of -0.77 (21.9th percentile), this represents normal volume ; whole brain volume measures 1,057,660 mm³, 2.0% below the reference mean. With a Z-score of -0.26 (39.7th percentile), this represents normal volume ; entorhinal cortex volume measures 3,766 mm³, 8.2% below the reference mean. With a Z-score of -0.55 (29.0th percentile), this represents normal volume ; fusiform gyrus volume measures 19,393 mm³, 2.9% above the reference mean. With a Z-score of 0.25 (59.9th percentile), this represents normal volume ; middle temporal gyrus volume measures 21,438 mm³, 0.5% above the reference mean.
