Synaptic extensions from the mossy fibers of the fascia dentata

In the hilar region of the rat hippocampus, filamentous extensions have been observed to originate from the en passant synaptic expansions on the so-called mossy fibers, which are the axons of the dentate granule cells. These extensions range in length from about 1 μm to 30 μm, are often branched, and appear to contact the processes of various cell types in… CONTINUE READING
