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

Rats readily learn to self-administer ethanol using a procedure where ethanol is introduced
in the presence of a sweetener. After gradual removal of the sweetener, sufficient quantities …

The purpose of this study was to assess the role of endogenous dopamine and glutamate
systems within the nucleus accumbens in modulating responses for oral 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 …

One of the functions of the mesolimbic dopamine (DA) system is to regulate the process of
reinforcement, a process that is thought to influence drug self‐administration. This study …

Background: The present study was designed to test directly whether a contextual stimulus
for access to ethanol would acquire the ability to enhance locomotor activity and dopamine …

Although operant ethanol self‐administration can increase accumbal dopamine activity, the
relationship between dopamine and ethanol levels during consumption remains unclear …

Mesocorticolimbic dopamine (DA) transmission has been implicated in the consummatory
and, more recently, the incentive-motivational aspect of ethanol's actions. The purpose of …

The alcohol deprivation effect is a temporary increase in the intake of, or preference for,
ethanol after a period of deprivation that may result from persistent changes in key limbic …

Background: This present study was designed to clarify the role of dopamine in the nucleus
accumbens during operant ethanol self‐administration by separating bar pressing (ethanol …
