The histogram shows the numbers of normal pyramidal neuron cells in different areas of the hippocampus of control, 40- and 60-minutes exposed mice (A-D). For measurement of viable neurons in each hippocampal imaging, a length of 350 µm of CA1, CA2, CA3 and 150 µ2 area of DG layer was selected. Healthy viable neurons were decreased significantly in 60 min compared to 40 min and control mice. Results were presented as Mean ± SEM. (n = 10 mice in each group). (*) indicates a statistically significant difference at the p < 0.05 level; (**) indicates a statistically significant difference at the p < 0.01 level; (***) indicates a statistically significant difference at the p < 0.001 level; (****) indicates a statistically significant difference at the p < 0.0001 level.
