Selective GABAA ??5 Benzodiazepine Inverse Agonist Antagonizes the Neurobehavioral Actions of Alcohol

Abstract

Overall, the results extend our previous findings by demonstrating that an alpha5-subtype ligand is capable of attenuating not only the rewarding action of alcohol but also its motor impairing and sedative effects. We propose that these actions are mediated in part by the alpha5-receptors of the hippocampus. The hippocampal alpha5-receptors could represent novel targets in understanding the neuromechanisms regulating the neurobehavioral actions of alcohol in humans.
