Mossy Fiber Sprouting in the Dentate Gyrus

WebNov 12, 1996 · At mossy fiber synapses, facilitation occurred at frequencies as low as once every 40 s and reached a magnitude of 6-fold. Frequency facilitation was dependent on a rise in intraterminal Ca 2+ and activation of Ca 2+ /calmodulin-dependent kinase II, and was greatly reduced at synapses expressing mossy fiber long-term potentiation. WebBecause the mossy fibers are axons of granule cells, the recurrent mossy fiber pathway provides monosynaptic excitatory feedback to these neurons that could facilitate seizure discharge. We used the pilocarpine model of temporal lobe epilepsy to study the synaptic responses evoked by activating this pathway. the oresteia libation bearers summary
