Accumbal dopamine during the baseline, transfer, and wait periods. (A) All groups are collapsed and presented as one. Arrows indicate the time of transfer from home cage into operant chamber and time during which the rat had access to the lever. Asterisks indicate P < .05 for dopamine when compared with the home cage baseline when all groups are collapsed: both days of 10% ethanol plus 10% sucrose or 10% sucrose (n = 37). (B) Each group is presented individually. For clarity only, representative error bars for each time period are shown. Plus signs indicate a significant day × solution interaction (P < .05) at the indicated time points.
