Figure 3.

Short-term repeated exposure to deltamethrin reduced the number of BrdU+ cells or cell proliferation in the dentate gyrus (DG) in hippocampus of adult mice. BrdU+ (green) cells were visualized by immunofluorescence staining in the DG region of the hippocampus (A). The number of BrdU+ cells is presented in bar graphs (B). The values represent mean cell number ± SEM per section from 10 sections per animal and 5 animals per group. An unpaired t test was used to determine significant difference between control and treatment. Asterisk indicates significantly different from control (t = 4.55; df = 8; p < .02). Scale bar = 400 µm.
