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 6. CA3-specific MFAs {CA3 Mossy Fiber-Associated} [mossy fiber associated cells] were not found to be monosynaptically innervated by MFs [mossy fibers]. Dendritic (gray) and axonal (black) arborizations, firing pattern, and immunoreactivities of are presentative MFA (abbreviations same as in Fig.3A). Note that the majority of the axons are located in the stratum lucidum and in the hilus, and also that the dendrites are not aligned with the mossy fiber pathway." |

| Notes |
| The articles in this cell type were part of the old MFA 03332p cell type. That cell type has been split into this cell type and the 02332p cell type. Axons is SR are borderline; however, Dr. Ivan Soltesz in an e-mail suggests that MFA axons synapse with CA3 granule cells in SR. Axons in SO less than 15%. |
