Ethanol associated behaviors have been linked to the β2‐subunit containing nicotinic acetylcholine receptors (β2*‐nAChR); however, there is conflicting evidence on ethanol‐induced changes in nAChR expression during and after chronic ethanol consumption. In this study, five male animals orally self‐administered ethanol for 18 ± 1 weeks. Animals were scanned with [123I]5‐IA‐85380 and SPECT prior to...
Gamma-aminobutyric acid (GABA)ergic adaptations contribute to the neurobiology of ethanol dependence and withdrawal. Clinical data suggest that tobacco smoking attenuates alcohol withdrawal symptoms. This study’s objective was to measure time-dependent cortical GABA levels with sobriety in ethanol-dependent patients with mild to moderate withdrawal severity, controlling for alcoholism-related neurotoxicity...
This review takes a translational neuroscience perspective on the role of glutamate systems in human ethanol abuse and dependence. Ethanol is a simple molecule with profound effects on many chemical systems in the brain. Glutamate is the primary excitatory neurotransmitter in the brain. Glutamatergic systems are targets for the actions of ethanol via its antagonism of the N-methyl-d-aspartate (NMDA)...
