From: Fitness is positively associated with hippocampal formation subfield volumes in schizophrenia: a multiparametric magnetic resonance imaging study

Name

Description

Tail

In the posterior part of the hippocampal formation

Subiculum

Divided into head and body; inferior part of the hippocampal formation

Presubiculum

Divided into head and body; inferior medial part of the hippocampal formation between the subiculum and parasubiculum (Brodmann 27)

Parasubiculum

Medial part of the hippocampal formation between the presubiculum and entorhinal cortex (Brodmann 49)

ML

Molecular layer: divided into head, body, and intermediate region, which contains parts of the subiculum or cornu ammonis (CA) fields

HATA

Hippocampus-amygdala transition area: superior medial part of the hippocampal formation

GCMLDG

Granule cell and molecular layer of the dentate gyrus: divided into head and body; between the molecular layer and CA4

Fissure

Anterior medial part of the hippocampal formation; white matter structure

Fimbria

Posterior superior part of the hippocampal formation; white matter structure

CA4

Cornu ammonis 4: inferior to the CA3 within the dentate gyrus

CA3

Cornu ammonis 3: superior to the dentate gyrus; includes CA2

CA1

Cornu ammonis 1: anterior lateral part of the hippocampal formation
