"Interneurons within layer II [of the entorhinal cortex] are described as MPNs [multipolar neurons], bipolar, basket, and chandelier cells. MPNs have polygonal, fusiform, or round cell bodies with multiple, sparsely spiny dendrites, extending in all directions, reaching layer I and deep into layer III. It has been described that the axons of MPNs travel to the white matter but also form local synapses within layer II [Tahvildari and A. Alonso 2005, Germroth 1991]. Morphologically they seem to be comparable to stellate cells within the MEC [medial entorhinal cortex] but there are electrophysiological differences. The family of MPNs contains VIP [vasoactive intestinal polypeptide], substance-P, CCK [cholecystokinin], SOM [stomatostatin], ENK, or GABA [gamma amino butyric acid] and in the LEC [lateral entorhinal cortex] also NPY [neuropeptide Y] [Kohler 1986]."
