FIG. 7.

Left: Group mean ± SE number of immobile bouts in male offspring during FS test 1 (n = 8–16 per group). Middle: Scatter plot from linear regression of immobile bouts against striatal 5-HIAA (top) and frontal cortex GABA (bottom). Right: Levels (ng/mg protein) of striatal 5-HIAA (top; n = 7–16 per group) and frontal cortex GABA (bottom; n = 8–16 per group) by treatment group (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) and behavioral paradigm (FI: fixed interval schedule of reward BE; FS: forced swim BE).

*Significant difference of at least p ≤ 0.05 from corresponding 0-NS control group value.
