"FIGURE 4. SOM [somatostatin] cells do not express ErbB4. (A) The distribu-
tion of SOM-immunoreactive somata is similar to PV [parvalbumin] cells; they
are mostly confined to layers so [stratum oriens], sp [stratum pyramidale], and hi [hilus]. In CA3 close to DG,
however, SOM cells are also frequently found in sr [stratum radiatum]. Note the dense
fiber plexus in slm [stratum lacunosum-moleculare] of CA1 that is the terminal field of O-LM [oriens--lacunosum-moleculare] cell
projections. Single channel images (B-C) show that most somata
are immunoreactive for either SOM (open arrows) or ErbB4
(arrows); however, one cell in sr coexpresses both markers (arrow-
head). The quantitative analysis (n = 3) reveals that the maximum
coexpression is 2% in both SOM cells (D) and ErbB4 cells (E)."
Interpretation notes: Glutamatergic and GABAergic SOM+ types in DG Smo_Smi_SG_H are probably ErbB4-
