OBSOLETE: The fascia dentata is the earliest stage of the hippocampal circuit. Its primary input is the perforant path from the superficial layers of entorhinal cortex. Its principal neurons are tiny granule cells which give rise to unmyelinated axons called the mossy fibers which project to the hilus and CA3. The fascia dentata of the rat contains approximately 1,000,000 granule cells. It receives feedback connections from mossy cells in the hilus at distant levels in the septal and temporal directions. The fascia dentata and the hilus together make up the dentate gyrus. As with all regions of the hippocampus, the dentate gyrus also receives GABAergic and cholinergic input from the medial septum and the diagonal band of Broca. [ ]

Term information


This class has been retired. Based on usage and FMA, we have added fascia dentata as a synonym for dentate gyrus. (Maryann Martone)[NIFSTD]





editor note

A quick perusal of definitions for fascia dentata suggests that it is sometimes used to refer to the entire dentate gyrus, in which case it should be a synonym, and sometimes to a specific cytoarchitectural field of dentate gyrus. More research is needed. In the meanwhile, I have not assigned it as a part of dentate gyrus, assigning instead the cytoarchitectural layers. (Maryann Martone)
