Mean neuronal cell counts and densitometric measurements ± SEM in autopsy (white bars), non-HS (shaded bars), and HS (black bars) patient groups. A–G, Sets of six immediately adjacent sections were stained for Nissl and the subunits α1, α2, α3, β2,3, and γ2. A, B, Densities of CA2 pyramidal cells (A) and granule cells (B).C–G, Optical density measurements in CA2 pyramidal cell layer (C), granule cell layer (D), inner molecular layer (E), outer molecular layer (F), and subgranular layer (G). H, I, Numbers of α1-subunit-positive interneurons per 625-μm-wide column through each stratum in CA2 (H) and CA3 (I). Nonparametric ANOVA pvalues are presented above data set, and significant post hoc results are indicated by asterisks(p < 0.05). *Difference compared to the autopsy or non-HS groups; **difference compared to the autopsy and non-HS groups.
