Quantification of the total area, the number of NeuN-positive cells, and the number of NeuN/DAPI double-positive cells in the hippocampus, CA1, CA2/3, DG, and stratum radiatum of the rat offspring prenatally exposed to BPA compared to those in the control group. The total area (a,b), cellular density (c,d), neuronal cell density (e,f), and percentage of neuronal cells (g,h) in the hippocampus, CA1, CA2/3, DG, and stratum radiatum were determined in the BPA group and compared with those in the vehicle control group. Hippocampus tissues (both sides) from three male and three female offspring were used in each treatment group. Data are presented as the mean ± SEM. *P value < 0.05. *Indicates a statistically significant difference between the BPA treatment and the vehicle control groups.
