Effects of adult methamphetamine (METH) exposure on the locomotor activity, novel spatial exploration, and social interaction after long-term methamphetamine abstinence. Histograms show total distance moved in the open field test (OFT) (A), time spent in the novel arm (%) in the novel spatial exploration test (B), and the sociability scores and social recognition scores in the social interaction assay (C and D, respectively). Data are expressed as the mean ± SEM; n = 10/group; *P < .05, comparison between the 2 indicated groups; unpaired t tests.
