Note: Bolded boxes indicate significantly different volumes between ASHS‐OAP and ASHS‐PMC (two tailed). Regions labeled by ASHS‐OAP that were significantly greater in volume compared to ASHS‐PMC included CA2/CA3/DG, SUB, ERC, and PHC. Regions labeled by ASHS‐PMC that were significantly greater in volume compared to ASHS‐OAP included CA 1 . Note that analyses were run on total volume; however, for completeness, we have reported left and right volumes for each MTL subregion.
