The reinforcing effects of alcohol consumption are mediated by acetaldehyde generated by catalase and other oxidizing enzymes such as cytochrome P-4502E1 in the brain. [60] Although acetaldehyde has been associated with some of the adverse and toxic effects of ethanol, it appears to play a central role in the activation of the mesolimbic ...
Alcohol is a tiny molecule, bathing nearly every cell in the body when we drink. The basic trajectory of liquor in the body is from a person's mouth, through the esophagus, to the stomach ...
Alcohol acts as a general central nervous system depressant, but it also affects some specific areas of the brain to a greater extent than others. Memory impairment caused by alcohol has been linked to the disruption of hippocampal function—particularly affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation ...
GABA B receptors also reduces the activity of adenylyl cyclase and Ca 2+ channels by using G-proteins with G i /G 0 α subunits. [4] GABA B receptors are involved in behavioral actions of ethanol, [5] [6] gamma-hydroxybutyric acid (GHB), [7] and possibly in pain. [8] Recent research suggests that these receptors may play an important ...

A GABA receptor agonist is a drug that is an agonist for one or more of the GABA receptors, producing typically sedative effects, and may also cause other effects such as anxiolytic, anticonvulsant, and muscle relaxant effects. [1] There are three receptors of the gamma-aminobutyric acid. The two receptors GABA-α and GABA-ρ are ion channels ...
Alcohol also direct affects a number of other neurotransmitter systems including those of glutamate, glycine, acetylcholine, and serotonin. [260] [261] The pleasurable effects of alcohol ingestion are the result of increased levels of dopamine and endogenous opioids in the reward pathways of the brain. [262] [263]
α 2 agonist: inhibits adenylyl cyclase activity, reduces brainstem vasomotor center-mediated CNS activation; used as antihypertensive, sedative & treatment of opiate dependence and alcohol withdrawal symptoms). Selected examples are: Brimonidine; Clonidine (mixed alpha2-adrenergic and imidazoline-I1 receptor agonist) Dexmedetomidine; Fadolmidine
