Effects of emetic agents on locomotion of rodent species.

<p>Vertical bars indicate median quadrants moved in the test chambers for each species group (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0060537#pone-0060537-g002" target="_blank">Fig. 2</a>). Animals were injected with saline (sc or ig) or the emetic agents apomorphine (sc), veratrine (sc), or CuSO₄ (ig) and observed for 40 min. Dark circles indicate raw movement scores for each animal and vertical lines represent the range of scores. * = p<0.05, Mann-Whitney U, comparison to saline control groups.
