Fig. 4. NeuN immunohistochemistry (A, C, E, G) and Fluoro-Jade B (F-J B) histofluorescence staining (B, D, F, H) in the dentate gyrus of the vehicle (A, B), scopolamine (SCO) (C, D), SCO+vanillin (E, F), and SCO+4-hydroxybenzyl alcohol (4-HBA) (G, H) groups. There is no difference in the distribution pattern of NeuN-immunoreactive neurons between all groups, and no F-J B–positive cells are detected in all groups. GCL, granule cell layer; ML, molecular layer; PL, polymorphic layer. Scale bar=100 µm. The bars indicate the means±SEM.
