No differences were observed in neurogenesis in mice, 22.5 months post exposure. PB+PER exposure did not alter neurogenesis in the dentate gyrus (DG) region in exposed animals at 22.5 months post exposure (B) as compared to controls (A). The depicted micrographs were taken using 20X (A,B), scale bars represent 50 μm. Histograms depict the manual quantification of the doublecortin (DCX) stain in the dentate gyri, as total number of cells within the DG.
