Negative affect promotes dysregulated alcohol consumption in non-dependent and alcohol-dependent animals, and cues associated with negative affective states induce withdrawal-like symptoms in rats. This study was designed to test the hypotheses that: (1) the kappa-opioid receptor (KOR) system mediates phenotypes related to alcohol withdrawal and(More)
Cocaine is a commonly abused central nervous system stimulant that enhances dopamine (DA) neurotransmission through its ability to block dopamine transporters (DATs). Recent evidence suggests there may be an interaction between DATs and D2/D3 autoreceptors that modulates cocaine's effects. The purpose of this study was to explore how D2/D3 autoreceptors(More)
The current experiment examined the effects of 10 days of chronic intermittent ethanol (CIE) exposure on anxiety-like behavior and home cage ethanol intake using a 20% intermittent access (M, W, F) paradigm in male and female Long-Evans rats. Withdrawal from alcohol dependence contributes to relapse in humans and increases in anxiety-like behavior and(More)
