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 …

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

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 …

The effects of microinjections in the ventral tegmental area (VTA) of the dopamine D2/D3
agonist quinpirole on ethanol‐and sucrosereinforced responding were tested. Two groups …

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 …

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

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 …

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 …

Dopaminergic neurotransmission in the nucleus accumbens may be an important factor in
ethanol reinforcement and genetically determined ethanol preference. This hypothesis was …

Rationale Novelty associated with behavioral testing has been shown to enhance
psychostimulant-and morphine-induced locomotor stimulation. Evidence has demonstrated …
