Figure 2: Spatial and ethological behaviors in the elevated plus-maze of mice exposed to chronic social defeat stress and ethanol administration. The test was performed for 5 min after 22 h of ethanol withdrawal. (a) Number of entries in the closed arms; (b) percentual number of entries in the open arms; (c) percentage of time spent in the open arms; (d) number of head dips performed; (e) percentage of head dips performed in the protected areas of the apparatus; (f) number of stretches performed; (g) percentage of stretch attend postures performed in the protected areas of the apparatus. Data are reported as mean ± SE (n = 8–9 animals per group). a, P < .05 relative to control-vehicle group; d, P < .05 relative to stress-ethanol group. |
