Brodmann's area 28; major gateway for neocortical input to the hippocampus; origin of the perforant pathway; a component of the medial temporal lobe memory system. (CSP) * The cytoarchitecturally well-defined area of multilaminate cerebral cortex on the medial aspect of the parahippocampal gyrus, immediately caudal to the olfactory cortex of the uncus. The entorhinal cortex is the origin of the major neural fiber system afferent to the hippocampus, the so-called PERFORANT PATHWAY (Stedman, 25th ed) (MSH) [NeuroLex: http://neurolex.org/wiki/Category:Secondary_olfactory_cortex].
Synonyms: secondary olfactory cortical area; area 28 of Brodmann; secondary olfactory areas
