Figure 2.

MAM exposure slightly increases excitability of CA1 pyramidal neurons in hippocampus in juvenile animals. Representative action potentials (a₁ and a₂) and summary graphs (b₁ and b₂) from juvenile and adolescent saline and MAM-exposed animals. (a₁ and b₁) Juvenile MAM-exposed animals had an increased spike number only with high current injection compared with saline controls (saline n=6, MAM n=7, *p<0.05). (a₂ and b₂) There is no difference in neuronal excitability in adolescent animals (saline n=11, MAM n=12, p>0.05).
