MRI-derived brain volumes

Brain region	Mean ± SD, (range) in cm3
Cerebral vault	1201.6  ± 111.6 (984.5–1,376.4)
Hippocampus*	2.5  ± 0.3 (2.0–3.1)
Parahippocampal gyrus*	4.2  ± 0.7 (2.8–5.6)
Superior temporal gyrus*	13.4  ± 1.6 (9.6–17.4)
Global atrophy	226.4  ± 66.2 (109.9–403.9)

Data are the raw volumes in cubic centimeters for the brain regions measured, including a measure of global atrophy.
