CA3 Perforant Path-Associated Projecting*
* indicates new v2.0 neuron type
Name Supertype (ID:Family:Type:Subregion)
CA3 (i)33000p-DG_1100-CA2_3000 Perforant Path-Associated Projecting* S162402:PPA Family:LM-targeting:CA3

Name derivation
This name is simple, borrows from the cited names, and describes the axons that invade DG and CA2. CA3 distinguishes these cells from perforant path-associated cells in other subregions.

"Figure 5. Visualization and firing patterns of a CCK-containing dendritic-layer-innervating cell. A, Reconstruction (Neurolucida, three dimensional) of cell B74a {CA3 Perforant Path-Associated Projecting*}, projected onto a plane approximately transverse to the hippocampus. This axis maximizes the overlap of layer boundaries recorded in individual coronal sections (thin blue lines); a best fit of ŇaverageÓ boundaries is shown by thick blue lines. The somato-dendritic domain is shown in full (red, 10 sections), the axon (black) only from four consecutive 70-[micro]m-thick sections also including the soma."
