Figure 2. Changes in consumption of 10% ethanol induced by NAc shell DAMGO.
Cumulative licks (A) over time following DAMGO (blue) or vehicle (grey) infusion (n=15); shaded areas show SEM. Introducing a 60-minute delay (B) following the injection prior to ethanol access did not change the post-injection time at which DAMGO increase cumulative licks (15 min delay, n=15; 60 min delay n=10). Systemic naloxone (Nalox; C) prevented DAMGO-induced increases in drinking and reduced drinking overall (n=5), *=versus vehicle, p<0.05.
