Convergent Projections from Perirhinal and Postrhinal Cortices Suggest a Multisensory Nature of Lateral, but Not Medial, Entorhinal Cortex (Cell Reports)

Doan et al. demonstrate with the use of tract tracing and in vitro electrophysiological recordings that the rat lateral entorhinal cortex receives convergent perirhinal and postrhinal inputs. They further argue that a comparable input organization scheme also exists in the primate, challenging the prevailing concept of parallel parahippocampal pathways to the hippocampus.
