Test–retest reliability of hippocampal subfield volumes in a developmental sample: Implications for longitudinal developmental studies

The hippocampus (Hc) is composed of cytoarchitectonically distinct subfields: dentate gyrus (DG), cornu ammonis sectors 1‐3 (CA1‐3), and subiculum. Limited evidence suggests differential maturation rates across the Hc subfields. While longitudinal studies are essential in demonstrating differential development of Hc subfields, a prerequisite for interpreting meaningful longitudinal effects is establishing test–retest consistency of Hc subfield...
