In the photomicrographs, representative image of cresyl violet staining (a–e), and FJC staining (f–j) in the piriform cortex after 2 h of KA challenge were presented. Arrows indicate the viable cell under cresyl violet staining (a–e). Viable cells were defined as cells with normal morphology, exhibiting round nuclei stained with cresyl violet-stained. In KA- treated groups and ASP+ KA treated groups, neurons appeared pyknotic, indicated by arrowheads (b and e). Neurons remained normal at 2 h after KA administration in the piriform cortex, (f–j). Scale bars: 100 μm. Magnification: 200x magnification
