Figure 1: Higher levels of exploration and locomotion and lower levels of anxiety in the open field test in male Formosan wood mice than in male C57BL/6 mice. (a) Time spent in and (b) number of entries into the central area and (c) the amount of defecation in the open field test. Distance travelled in the (d) central area and (e) peripheral area, and (f) total distance travelled in the open field test. The vertical line above each bar represents the SEM (n = 9 for each group). *P < 0.05, **P < 0.01 and ***P < 0.001, compared with C57BL/6 mice. SEM: Standard error of the mean.
