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 …

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

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

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 …

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 …

Alcohol-drinking male Wistar rats consuming a 10% v/v ethanol solution presented in a free
choice with water did not alter their intake of ethanol during 5 days of treatment with …

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 …

It appears clear that ethanol reinforcement, like that of many abused drugs, utilizes the
mesolimbic DA pathways. From the data presented on microinjection of DA agonists and …

The neurobiological processes by which ethanol seeking and consumption are established
and maintained are thought to involve areas of the brain that mediate motivated behavior …
