The mossy fiber pathway
The pathway allows sensory information to reach the hippocampus for encoding. The mossy fiber pathway itself projects to CA3. Repetitive stimulation of its neurons leads to progressive use-dependent synaptic depression. These short-term changes in plasticity have been shown to be mediated by sodium channels … See more In the hippocampus, the mossy fiber pathway consists of unmyelinated axons projecting from granule cells in the dentate gyrus that terminate on modulatory hilar mossy cells and in Cornu Ammonis area 3 (CA3), a region … See more In the mouse, a single mossy fiber projection may make as many as 37 contacts with a single pyramidal cell, but innervates only about a dozen different pyramidal cells. In contrast, a single CA3 pyramidal cell receives input from about 50 different granule … See more Mossy fibers in the hippocampus project from the dentate gyrus to CA3. The pathway consists of varicose granule cell axons that terminate on the dendrites of hilar mossy cells and pyramidal cells in CA3.

WebDec 4, 2001 · At the mossy fiber synapse on CA3 pyramidal neurons, both protein kinase A (PKA) and protein kinase C pathways are thought to play key roles in long-term enhancement of synaptic strength (36–38). We therefore investigated whether activation of adenylyl cyclase or PKC was able to mimic the induction of LTP (Fig. 4 ).
