A: Prenatal treatment – Pregnant dams received propionic acid (PPA) or vehicle once a day from gestation day 12–16 to yield the prenatal PPA and 5VEH groups. Lipopolysaccharide or vehicle was administered once a day on gestation days 15 and 16 to yield the prenatal LPS and 2VEH groups. B: Postnatal treatment – Half the pups in all litters received PPA every second day (2 times a day) from P10–18 with the other half receiving vehicle. C: Behavioral testing in adolescence – EPM: elevated plus maze; O/F: open-field activity and thigmotaxis; behavioral data collected from P45–51 reported elsewhere.
