The University of Texas at Austin, PHAR Pharmacology, Austin, Texas 78712, USA
Synapse 60:158-64. 2006..In addition, the blunted ethanol-evoked DA response in the D2 knockouts may contribute, in part, to some of the behavioral deficits previously observed in response to ethanol...
- A 3-day exposure to 10% ethanol with 10% sucrose successfully initiates ethanol self-administrationJennifer Carrillo
College of Pharmacy, Department of Pharmacology, The University of Texas at Austin, Austin, TX 78712, USA
Alcohol 42:171-8. 2008..Blood alcohol concentrations were 4.5 mM 20 min after consumption began. We conclude that initiation and establishment of ethanol self-administration will occur using this modified sucrose-fading procedure...

Cell and Molecular Biology, College of Pharmacy, University of Texas, Austin, TX 78712 0125, USA
J Pharmacol Exp Ther 329:625-33. 2009..These observations suggest that an increase in Ca(2+) release from intracellular stores via 5-HT(2C) receptor activation is involved in the ethanol-induced enhancement of GABA release onto VTA-DA neurons...
- Characterization of probe and tissue factors that influence interpretation of quantitative microdialysis experiments for dopamineAmanda Tang
Division of Pharmacology and Toxicology, College of Pharmacy, University of Texas at Austin, Austin, TX 78712, USA
J Neurosci Methods 126:1-11. 2003..These findings are consistent with a decrease in physiological viability of the dopamine nerve terminals surrounding the probe during a long-term experiment...
- Mu (mu) opioid receptor regulation of ethanol-induced dopamine response in the ventral striatum: evidence of genotype specific sexual dimorphic epistasisMartin O Job
Division of Pharmacology, College of Pharmacy, University of Texas, 1 University Station, Austin, TX 78712, USA
Biol Psychiatry 62:627-34. 2007..Mu (mu)-opioid (MOP) receptors modulate accumbal dopamine activity, but it is not clear whether MOP receptors are involved in the mechanism of ethanol-stimulated accumbal dopamine release...
- Ethanol preference is inversely correlated with ethanol-induced dopamine release in 2 substrains of C57BL/6 miceVorani Ramachandra
University of Texas at Austin, Pharmacology PHAR, Austin, Texas 78712, USA
Alcohol Clin Exp Res 31:1669-76. 2007..Differences in ethanol-induced dopamine release in the ventral striatum could contribute to this variability in drinking behavior as dopamine has been implicated in the reinforcing properties of ethanol...
- Effect of gender and estrous cycle on the pharmacokinetics of ethanol in the rat brainDonita L Robinson
College of Pharmacy, University of Texas, Austin, Texas, USA
Alcohol Clin Exp Res 26:165-72. 2002..This study used quantitative microdialysis to measure ethanol pharmacokinetics in the nucleus accumbens after a moderate dose of ethanol, comparing males with females and females across the estrous cycle...
- Ethanol increases extracellular dopamine concentration in the ventral striatum in C57BL/6 miceAmanda Tang
College of Pharmacy, University of Texas at Austin, USA
Alcohol Clin Exp Res 27:1083-9. 2003..Mesolimbic dopamine is thought to play a role in the reinforcing properties of ethanol, but ethanol-induced changes in extracellular dopamine in the ventral striatum have not been well characterized in mouse models...
- Kappa-opioid receptor modulation of accumbal dopamine concentration during operant ethanol self-administrationWilliam M Doyon
Department of Neuroscience, Baylor College of Medicine, Houston, TX 77030, USA
Neuropharmacology 51:487-96. 2006..Despite these neurochemical changes, NOR-BNI did not alter operant responding or ethanol intake, suggesting that the KOPr is not involved in ethanol-reinforced behavior under the limited conditions we studied...
