Figure 3

Effects of nicotine (A), chlorpyrifos (B), and combined treatment (C) on 5HT levels in frontal/parietal cortex (f/p) and temporal/occipital cortex (t/o), shown as the percent change from control values (see original values in Supplementary Table 3). Multivariate ANOVA for each treatment appears at the top of the panels. Because treatment did not interact with the other variables, only the main treatment effects are given. Panel (D) shows the simple main treatment effects, collapsed across regions and ages, and combined for males and females because of the absence of a treatment × sex interaction. Abbreviation: NS, not significant.
