D1/D5 dopamine receptor-selective drugs differentially modulate frequency-modulated tone discrimination learning of 6JOla and 6J mice. Mice were trained in daily sessions to discriminate between rising and falling frequency-modulated tones. After session 1, they received intraperitoneal injections of vehicle (A), SCH23390 (B), SKF38393 (C), SKF83822 (D), SKF83959 (E), or a combination of SKF83822 and SKF83959 (F). Arrows indicate the approximate injection time. Discrimination rates D are presented as means ± S.E.M. n refers to the number of mice. ANOVA values are described in the text. *P < 0.05, significantly different from the corresponding value of the 6J subpopulation (unpaired t-test).
