"At low doses, alcohol enhances the action of GABA, the brain's primary inhibitory neurotransmitter, leading to reduced anxiety and altered personality and judgment with increased consumption."
"Higher doses of alcohol affect movement and coordination, while very high doses inhibit brain functions controlling breathing and heart rate, increasing the risk of death."
"Alcohol stimulates dopamine release, which may underlie feelings of pleasure, and inhibits glutamate, a neurotransmitter essential for memory production, explaining memory loss during intoxication."
Alcohol affects the brain by enhancing GABA, which reduces anxiety and alters personality at low doses. Higher doses impair movement and coordination, while very high doses can inhibit breathing and heart rate, posing a risk of death. Alcohol also stimulates dopamine release, contributing to pleasure, and inhibits glutamate, affecting memory formation. Upon entering the body, alcohol is metabolized by alcohol dehydrogenase into an irritating aldehyde, which is further processed into acetate and carbon dioxide.
