The term area 48 of Brodmann refers to a subdivision of the cytoarchitecturally defined hippocampal region of the cerebral cortex in the human. It is located on the medial surface of the temporal lobe. Cytoarchitectually it is bounded rostrally by the perirhinal cortex 35 and medially by the presubiculum. While described by Brodmann ( Brodmann-1909 ), it was not included in his areal maps of human cortex ( Brodmann-1909; Brodmann-1910 ).
