Functional specificity of mossy fiber innervation of GABAergic cells in the hippocampus. Szabadics J, Soltesz I J Neurosci, 2009 Apr 1, 29 (13), pages: 4239 - 4251 PMID: 19339618; DOI: 10.1523/JNEUROSCI.5390-08.2009 |
 "Figure 5. MFs [mossy fibers] are monosynaptically connected to SLCs [spiny lucidum cells] {CA3 Spiny Lucidum} in CA3. A, Dendritic (gray) and axonal (black) arborizations, firing pattern, the spiny dendritic surface, and immunoreactivities of are presentative SLC that received monosynaptic MF inputs. Note that the SLC dendrites aligned with the stratum lucidum. Asterisk marks the severed main (presumably long distance projecting) axon of the SLC on the surface of the slice. Circle graph indicates the relative proportion of the SLCs (shaded black in the circle graph) that received monosynaptic input from MFs of the 46MF-SLC pairs (BIO, biocytin; ori, stratum oriens; pyr, stratum pyramidale; luc, stratum lucidum) (calibration for the firing pattern: 20 mV, 200 ms). ... D, An example SLC that projected from the CA3 to the DG. Note that the main axon exited the surface of the slice (asterisk)." |
