Figure 1. Cresyl violet stain shows histopathological changes in pyramidal cells within 1 mm of the hippocampus CA1 area in the Sham group (A), 2VO group (B), and EBN groups with different doses (C & D) under light microscope. Arrows show the viable, well-defined neuronal cell with a distinct nucleus and fairly stained cytoplasm in A (Sham), C and D (EBN). In Group B (2VO), the arrow shows the pyknotic nuclei along with shrunken cytoplasm.
