FIG. 4.
Group mean ± SE monoamine neurotransmitters (ng/mg/protein) levels in male offspring of indicated brain regions.
NS: 0-NS, no Pb, no stress; PS: prenatal stress, no Pb exposure; Pb: Pb exposure, no prenatal stress; Pb + PS: Pb exposure and prenatal stress. *Significant difference of at least p ≤ 0.05 from corresponding 0-NS control group value following initial ANOVA (Table 3). Plots with black FS bars indicate significant interactions of Pb, PS, or both with BE in the overall ANOVA. Sample sizes: frontal cortex, 7–17 per group; hippocampus, 8–17 per group; striatum, 7–16 per group.
