The dentate gyrus then synapses on pyramidal cells in CA3 via mossy cell fibers.

It receives feedback connections from mossy cells in the hilus at distant levels in the septal and temporal directions.

Normal dentate gyrus demonstrates a clear segregation of granule cells and hilar mossy cells, which are identified, respectively, by their expression of calbindin and calretinin.

CGE-derived cells include GABAergic interneurons, spiny interneurons, mossy cells, pyramidal and granule neurons, and even oligodendrocyte and astrocyte glial cells.

Then the Other Professor got up, and began: Little Birds are dining Warily and well, Hid in mossy cell: Hid, I say, by waiters Gorgeous in their gaitersI've a Tale to tell.

Perforant path input from EC layer II enters the dentate gyrus and is relayed to region CA3 (and to mossy cells, located in the hilus of the dentate gyrus, which then send information to distant portions of the dentate gyrus where the cycle is repeated).
