Figure 2.
Immunohistochemistry. Panels depict ChAT (A–F) and parvalbumin (G–I) immunohistochemistry in the MS/VDB (A, D, G), HDB (B, E, H), and nBM/SI (C, F, I) of control (A–C) and BF-lesioned (D–I) rats. A loss of cholinergic (ChAT-positive) basal forebrain neurons is apparent in the BF-lesioned rats (D–F), but parvalbumin-immunoreactive neurons are preserved at the lesion site (G–I).
