The mossy fiber pathway
WebFeb 27, 1998 · Hippocampal slices from rat brains were prepared as described previously ().The mossy fiber pathway was activated by low-intensity stimulation of the dentate gyrus or stratum lucidum ().In a typical experiment, tetanic stimulation induced LTP in a CA3 pyramidal cell (Fig. 1A). Moreover, excitatory postsynaptic currents (EPSCs) were blocked … WebUniversity of North Carolina, Charlotte. BIOL. BIOL 4279
The mossy fiber pathway
Did you know?
Mossy fibers are one of the major inputs to cerebellum. There are many sources of this pathway, the largest of which is the cerebral cortex, which sends input to the cerebellum via the pontocerebellar pathway. Other contributors include the vestibular nerve and nuclei, the spinal cord, the reticular formation, and feedback from deep cerebellar nuclei. Axons enter the cerebellum via the middle and infe… WebThe entorhinal cortex transmits its signals from the parahippocampal gyrus to the dentate gyrus via granule cell fibers known collectively as the perforant path. The dentate gyrus then synapses on pyramidal cells in CA3 via mossy cell fibers. ... EC → DG via the perforant path (synapse 1), DG → CA3 via mossy fibres (synapse 2), CA3 → CA1 ...
WebWhatever the events are that trigger mossy fiber sprouting, presumably they are transduced to granule cells as molecular cues that activate signaling pathways to coordinate mossy fiber growth and synaptogenesis. c-Fos … Web10 rows · The major mossy fiber pathways and the climbing fiber projection have unique origins in the ...
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. They form three morphologically different synaptic terminals, … See more • Mossy fiber (cerebellum) See more WebCustomizable Services.
