Characteristics of the treatment groups and drug concentrations.

Treatment groups, ages at the time of locomotor activity tests in novel cages, and body weights at the beginning and end of treatments are showed. Drug concentrations were analysed from serum samples collected after the locomotor activity tests and presented in mM (lithium) or µM (lamotrigine). Data are means ± SEM. *p<0.05, **p<0.01, ***p<0.001 compared to body weight at the beginning of treatments (paired t-test), #p<0.05 for the genotype difference (unpaired t-test).
