The effect of saline and salicylate on behavioral performance of trained rats. Panels A and B: Performance of 7 rats on Quiet trials on the days before (Days −4 to −1), during (Day 0) and after (Days 1 to 4) systemic treatment with saline or salicylate. 2 h after saline injection (Day 0; panel A), all of the rats correctly identified Quiet trials as such, whereas 2 h following injection with salicylate (200 mg/kg IP), 6 of 7 rats misidentified Quiet trials as NBN trials indicating the presence of a steady phantom sound (Day 0; panel B). The horizontal black line indicates the one-tailed criterion for significance.
