Fig. 4. Nissl staining of neuronal morphology in hippocampal DG region. (A) Representative light micrographs of Nissl-stained DG hippocampal cells. Scale bar = 100 μm. (B) Quantitative analysis of Nissl cells in the DG regions of the hippocampus. n = 5–8 mice per group. #P < 0.05 vs. WT-saline, *P < 0.05 vs. APP/PS1-saline, **P < 0.01 vs. APP/PS1-saline.
