Figure 3. Effects of yohimbine on conditioned reinforcement by sucrose cues.

Figure 3.

A) Number of entries into nosepoke holes that resulted in presentations of the CS+ versus CS− following injections of yohimbine (orange) versus vehicle (blue) in rats that underwent Pavlovian conditioned with 10% sucrose reward (n=8 males), mean +/− SEM, *, p < 0.05. B) Total port entries during conditioned reinforcement sessions after yohimbine (orange) versus vehicle (blue), mean +/− SEM. C) Scatterplot showing entries into the CS+-paired nosepoke versus the CS− nosepoke from individual sessions after yohimbine (orange) or vehicle (blue). Inset histogram shows the distribution of sessions based on the difference in the number of CS+ versus CS− nosepokes.
