"The hippocampus proper is made up of CA1, CA2 and CA3 fields 8. Although there is a lack of consensus regarding terms describing the hippocampus and the adjacent cortex, the term hippocampal formation generally applies to the dentate gyrus (often considered to include CA4 and frequently called the hilus), CA1, C2, CA3, the subiculum, and the entorhinal cortex 1-8. NB: CA is an abbreviation of cornu Ammonis."

"The hippocampus is best imaged in the coronal plane, angled perpendicular to the long axis of the hippocampal body. The three parts of the hippocampus (head, body and tail) can be identified based on morphology and by using local landmarks 3."

"direct neocortical projections: the entorhinal cortex also receives direct input from the superior temporal gyrus, ventral insular cortex, posterior orbitofrontal cortex, dorsolateral frontal cortex, medial frontal cortex, cingulate cortex, and retrosplenial cortex"
"There are both intrinsic and extrinsic pathways. The intrinsic connections are those within the hippocampus, whereas the extrinsic pathways represent the afferent (input) and efferent (output) connections 8. Historically, these connections were seen as part of the Papez circuit. Modern understanding has evolved beyond this classical view with additional inputs and outputs being recognised 8."
