Mean proportion time freezing (±SEM) during the first two minutes before a CS presentation by day (a, b) and in between CS presentations by day (c, d) for Experiment 1 (a, c) and Experiment 2 (b, d). There were no significant differences between groups for either Experiment 1, drug administration beginning Day 1 (a) or Experiment 2, drug administration beginning Day 2 (b) for freezing during the first two minutes before a CS presentation. In Experiment 1, there were no significant differences between groups on Days 2 or 6 for freezing in between CS presentations, however the baclofen group froze significantly more than the saline group on Day 4 (c; *=significant difference compared to the saline group, p<0.05). In Experiment 2, there were no significant differences in freezing in between CS presentations for any day (d).
