CA1 (-)1113p-CA3 10001-SUB 110 wide oriens-bistratified (wide o-bi) neurons
|
Merger status:
|
No current merger proposals.

Related classes:
|
CA1 (-)0113p-SUB111 TH-ORP-DP-OR contains "classic" oriens-bistratified cells (aka O-R cells), as defined by Maccaferri (2000).
|
Notes:
Axonal arbor is very wide and extent of projections is somewhat unclear. The subject is not discussed in Katona (1999) and Losonczy (2002) admit that the arbor was likely "severely truncated" due to slicing.
It is possible that the cells closest to subiculum only project there and those closest to CA3 only project there. However, it seems clear that some percentage (Losonczy guesses 40%) project to both subregions.

I question SM of the Sub [for Fig. 5A in Losonczy et al., 2002]. I think just PL + SP, making the pattern 011 in the Sub. Correction, I see SM now, but why not PL?

Part of the text argues against axons in SLM.

|
The projecting axons of this cell [Fig. 5A in Losonczy et al., 2002] would hit CA2 before CA3. Does CA2 need to be added?
|
|
I do not think the top cell [Fig. 5A in Losonczy et al., 2002] goes with the other two [Figs. 5B,D in Losonczy et al., 2002]. - CW

The cell in Losonczy's Fig 5a does not project to CA3, though the authors speculate that 40% of oriens-bistratified cells project both there and to the subiculum.
