hippocampus

One may see there the corresponding hypointensity of Ammon's horn and the dentate gyrus, in lengthened form, from the back side to the front and from the top to the bottom, with the extreme anterior end folded upon itself (Fig.

The human brain presented a similar structure, with the retrocommissural hippocampus, where Ammon's horn and the dentate gyrus are folded upon themselves, in its anterior part (Fig.
