The human parahippocampal cortex (PPH) is largely coincident with areas TH and TF of von Bonin and Bailey (1951). PPH in the non-human primate is related to visuospatial, visual and auditory information, and is one the main links in memory circuitry through projections to the entorhinal cortex and the CA1/Subiculum border. PPH lies at the caudal part of the parahippocampal gyrus. PPH borders are macroscopially indistinct, rostrally with perirhinal cortex (BA 35 and 36), and caudally with visual association areas (area TEO and V5). PPH medial border is the hippocampal fissure (or parieto-occipital fissure caudally); the lateral border is the collateral and occipito-temporal sulci. Structurally, PPH is mesocortex interposed between the parasubiculum or presubiculum and visual association cortex. The correlation with MRI features (taken on a Phillips Intera 1.5 T machine, 256x512 matrix, 2 mm thick sections with no interval between adjacent sections)allows the delimitation of PPH, based on coronal sections orthogonal to the AC-PC line and topological relationship to nearby sulci.The anterior limit is 2 mm caudal to the last section showing the gyrus intralimbicus (caudal end of the tip of the uncus). The posterior limit was established at the level where the fimbria is cut tangentially. Preliminary results in a series of 20 control subjects, 20 cases with mild cognitive impairment, 10 cases with vascular dementia and 10 cases with mixed dementia (ethically approved by local committees)are presented.
