A posterior and upward extension of the dentate gyrus, forming a transitional area between the dentate gyrus and the indusium griseum[BTO]. TODO - existing definitions, synonyms and relationships in existing AOs seem contradictory; to be resolved. We take the dentate gyrus relationship from BTO, and it is also implied by the FMA synonym. However, FMA says archiortex (embryonic archicortex corresponds to the cortex of the dentate gyrus and hippocampus) and NIF says limbic lobe (which is more general than hippocampus).
