Fig. 7.

Dose–response of unilateral infusions of RY (0.0–40 μg) in the hippocampus (n = 7) (A), NACC (n = 5) (B), and VTA (n = 5) (C) on a concurrent fixed-ratio (FR4) schedule for EtOH (10% v/v) and saccharin-maintained (0.025% w/v) (SACC) responding. Immediately after the microinfusions, rats were placed in the operant chamber to lever press for a 60 min session. *p ≤ 0.05 versus the aCSF control condition values by ANOVA and post hoc Newman–Keuls test. Again, RY failed to alter EtOH or saccharin-maintained responding in the NACC and VTA.
