"No SS [somatostatin] immunoreactivity was found in any 5-HT[serotonin] 3 R[receptor]-expressing neurons, although single SS-immunopositive or 5-HT 3 R-expressing neurons were identified readily in cortex and hippocampus."
Interpretation notes: Glutamatergic and GABAergic SOM+ types in DG SMo_SMi_SG_H are probably 5HT-3- by contrapositive logic

"Table 3. Number of calretinin- and/or parvalbumin-immunoreactive nonpyramidal cells "
Interpretation notes: Glutamatergic and GABAergic CR+ types in DG H are probably PV-; Clopper-Pearson confidence interval lower bound = 95.4% (n = 79/79)
