Maturation of Hippocampal Subfields in Young Adulthood and Its Relationship With Cognition.

ABSTRACT: The hippocampus is a key brain region for memory and cognitive functions, which consists of distinct subregions with different developmental trajectories throughout adolescence. However, trajectories of hippocampal subfield change in young adulthood remain uncharacterized, as is their potential relationship with cortical brain aging and cognitive ability during this time. We conducted two magnetic resonance imaging (MRI) follow-ups of a prenatal birth cohort in young adulthood and studied the effects of chronological age and cortical brain age on the volume of hippocampal subfields in the early 20s (n = 109; 51% men) and late 20s (n = 251; 53% men) and how these age-related volumetric changes might relate to full-scale IQ (FSIQ). We showed that CA1 and CA4DG subfields continue to grow in t
