Data are average density of terminal fiber labeling across the entorhinal (ER) efferent regions. Density of fiber labeling was averaged for each of the dentate-gyrus (DG) projecting bands of the entorhinal cortex. See text for details of how fiber density was quantified. Only one injection site was located in the LEA medial band and the MEA medial band.
No injection sties were clearly located in the intermediate band of the MEA. Legend: -, no observed label; +, negligible; ++, very sparse; +++, sparse; ++++, moderately dense; +++++, dense; ++++++, very dense.
