Table 3.

Mean hippocampal volumes derived from the proposed ex vivo atlas (FreeSurfer v6.0), the in vivo atlas (FreeSurfer v5.3), the UPenn atlas (Yushkevich, et al., 2009), and two histological studies of the hippocampus (Simic, Kostovic, Winblad, & Bogdanovic, 1997) (Harding, Halliday, & Kril, 1998). All the volumes are in cubic millimeters. The UPenn atlas is available at http://www.nitrc.org/projects/pennhippoatlas/; we computed its volumes from the most likely labels.
