Photomicrograph of H&E-stained brain sections in all rat groups. Control: hippocampus showing average Cornu Amonis (CA1), (CA2), (CA3), average dentate gyrus (DG), and average blood vessels (black arrow) in (DG). TAA: showing scattered degenerated neurons (black arrow) in Cornu Amonis (CA1), (CA2), average inter-neuron area (blue arrow), and average blood vessels (red arrow). LDR: showing average dentate gyrus (DG) with mildly congested blood vessels (black arrow) and normally shaped and sized neurons. BA: There was no histopathological alteration and the normal histological structure of the hippocampus and striatum of the cerebrum. TAA+LDR: showing average Cornu Amonis (CA1), (CA2), (CA3), normal dentate gyrus (DG), and regular inter-neuron area (black arrow) in (DG). TAA+BA: showing average Cornu Amonis (CA1), (CA2), (CA3), normal dentate gyrus (DG), regular inter-neuron area (black arrow), and normal blood vessels (blue arrow) in (DG). TAA+LDR+BA: showing normal Cornu Amonis (CA1), (CA2), scattered degenerated pyramidal neurons (black arrow) in (CA3), eosinophilic plaque-like areas (blue arrow), and regular blood vessel (red arrow) (H&E X 200)
