With a Z-score of -0.10 (46.1th percentile), this represents normal volume ; whole brain volume measures 1,005,460 mm³, 3.2% above the reference mean. With a Z-score of 0.40 (65.5th percentile), this represents normal volume ; entorhinal cortex volume measures 3,614 mm³, 1.6% below the reference mean.
