Effects of phencyclidine treatment, nicotine history and the combined insults on adolescent mice, as assessed in the open field arena: (A) locomotor activity and (B) anxiety-like behavior. CT: Control group (♀ = 12, ♂ = 16); NIC: Nicotine-exposed group (♀ = 14, ♂ = 14); PCP: Phencyclidine-treated group (♀ = 14, ♂ = 14); PCP-NIC: Phencyclidine-treated and nicotine-exposed group (♀ = 12, ♂ = 14). Values are means ± SEM. *p < 0.05, **p < 0.01, ***p < 0.001. @p < 0.05, Day 1 vs. Day 2 or Day 1 vs. Day 3 within each experimental group. ###p < 0.001, phencyclidine-treated (PCP and PCP-NIC) vs. phencyclidine non-treated (CT and NIC) mice.
