Hippocampus and Entorhinal Complex: Functional Imaging

  • Reference work entry
Encyclopedia of Pain

Synonyms

Entorhinal cortex and hippocampus; Functional imaging; Neuroimaging; Parahippocampal region

Definition

The hippocampus is comprised of the dentate gyrus and the CA1, CA2, and CA3 pyramidal cell fields. The hippocampal formation consists of the hippocampus and the subiculum. The adjacent entorhinal, perirhinal, and parahippocampal cortices comprise the parahippocampal region (Fig. 1). These limbic subregions differ in their cellular organization and connectivity but are commonly implicated in memory and emotion processing.

(Left) Medial view of the human brain outlining the perirhinal cortex (orange); parahippocampal cortex (red); and entorhinal cortex (yellow). (Right) Section of the temporal lobe showing the components of the hippocampal/entorhinal complex in some detail: the dentate gyrus (pale green); the CA1 and CA3 hippocampal fields (green) that make up the hippocampus proper; the subiculum (pink); the...
