"In the dentate gyrus, the majority (95%) of hilar SOM[somatostatin]-containing neurons were also shown
to be immunoreactive for NOS [nitric oxide synthase]. In the same region, only a negligible
number (5%) of PV[parvalbumin]-positive cells contained NOS immunoreactivity
(Dun et al., 1994; Divila et al., 1995)."
Interpretation notes: Glutamatergic and GABAergic nNos- types in DG H are probably SOM- by contrapositive logic; Clopper-Pearson confidence interval lower bound = 93.2% (n = 771/812)

"In these experiments, all the cells of the hippocampus immunoreactive for somatostatin were strongly immunoreactive for mGluR[metabotropic glutamate receptor]lalpha, and likewise the cells immunoreactive for mGluRla were also immunoreactive for somatostatin (Figures 2A and 2B)."
