Anxiety behavior and locomotor activity. SM- and BP-reared adults were tested for anxiety and exploratory/locomotor activity in the open-field and elevated plus maze (EPM). SM- and BP-reared adult animals showed no differences in time spent exploring the anxiety-inducing center zone of the open-field (A), but SM-reared animals did spend a greater percentage of time in the anxiety-inducing open-arms of the EPM (B), compared to BP-reared adult animals. In terms of locomotor activity, SM-reared adult animals of both sexes showed transient hyperactivity in both the first 5 min of the open-field test (C) and the 5 min EPM test (D), compared to BP-reared counterparts. Bar graphs represent means + SEM. ■, BP-reared adult offspring; □, SM-reared adult offspring. *P < 0.05, ns = not significant.
