Figure 5. Extinction responding in context B: Cue versus no cue (Exp 1 vs 2). (A).
Extinction responding: Total number of active lever presses in rats tested in the extinction context (context B) in the cue or no-cue conditions after 1 day, 1 week, or 1 month of withdrawal. # Different from no cue, p<0.05 (B) Extinction time course (1 day): Number of active lever presses over six 1-h extinction sessions in rats tested in context B in the cue or no-cue conditions after 1 day of withdrawal. (C) Extinction time course (1 week): Number of active lever presses over six 1-h extinction sessions in rats tested in context B in the cue or no-cue conditions after 1 week of withdrawal. (D) Extinction time course (1 month): Number of active lever presses over six 1-h extinction sessions in rats tested in context B in the cue or no-cue conditions after 1 month of withdrawal. # Different from no cue, p<0.05
