The present experiment tested the effects of intraaccumbens injections of dopamine (DA)
agonists and antagonists on operant responding reinforced by sucrose and sucrose/ethanol …

Abstract Long-Evans rats (N= 3) were trained to lever press on a fixed-ratio 4 (FR 4)
schedule with ethanol (10% v/v) presented as the reinforcer. Each rat received a total of six …

Rats initiated to self-administer 10% ethanol (v/v) in an operant situation using the sucrose-
substitution technique received bilateral n. accumbens or caudate nucleus microinjections of …

Six male Long–Evans rats were trained to self-administer 10% ethanol (v/v) during 30 min
operant sessions. A licking response on an empty drinking tube resulted in the presentation …

From previous microinjection studies, a reciprocal feedback between the nucleus
accumbens and the ventral tegmental area (VTA) has been implicated in the reinforcing …

Background: Nucleus accumbens dopamine has been shown to play a role in the
processing of behaviorally relevant stimuli and to mediate ethanol‐reinforced responding …

It was determined whether ethanol palatability in rats could be changed by manipulating the
reinforcement experienced during limited access consumption. During the first 3 days of the …

Three experiments examined the behavioural, pharmacological and neural specificity of the
previously reported potentiation of responding with conditioned reinforcement following intra …

This study tested the role of dopamine receptors in the medial prefrontal cortex (mPFC) in
the onset, maintenance, and termination of ethanol and sucrose‐reinforced responding. Two …

Rats, initiated to self-administer 10%(v/v) ethanol in an operant situation using the sucrose-
fading procedure, received bilateral n. accumbens microinjections of d-amphetamine prior to …
