The Dopamine Response in the Nucleus Accumbens Core–Shell Border Differs From That in the Core and Shell During Operant Ethanol Self-Administration
Alcoholism: Clinical and Experimental Research Published Online: 30 Apr 2009

We conclude that dopamine responses to operant ethanol self-administration are subregion specific. After operant training, accumbal dopamine responses in the core and shell occur when cues that predict ethanol availability are presented and not when the reinforcer is consumed. However, core–shell border dopamine responses occur at the time of the cue and consumption of the reinforcer.
