Figure 5.
Maze comparison after yohimbine treatment: In both mazes, percentage of time animals spent in the open areas (A) and number of head dips (B) were decreased following yohimbine exposure. Start latencies (C) were increased in yohimbine-treated animals compared to SAL controls. The number of closed area entries (D) in both mazes was reduced after yohimbine treatment compared to controls. In the Plus, yohimbine-treated animals exhibited a trend towards significance in percentage of time spent in the center region (E). No difference in distance traveled (F) in the open-field was observed. *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001. Yohimbine: N = 8/maze; SAL: N = 6/maze.
