Alcohol is believed to mimic GABA’s effect in the brain, binding to GABA receptors and inhibiting neuronal signaling. Alcohol also inhibits the major excitatory neurotransmitter, glutamate, particularly at the N-methyl-d-aspartate (NMDA) glutamate receptor.
Does alcohol increase or decrease GABA?
Alcohol stimulates GABA receptors, and thereby dampens activity in the brain. It is thought that this is why it produces an immediate reduction of anxiety, and overdoses can lead to coma. If there is a constant supply of alcohol, however, the brain receptors adapt by reducing GABA receptors.

Does alcohol release serotonin?
Animal studies also have found that acute alcohol exposure elevates serotonin levels within the brain (LeMarquand et al. 1994b; McBride et al. 1993), suggesting either that more serotonin is released from the serotonergic axons or that the neurotransmitter is cleared more slowly from the synapses.
Is alcohol a GABA agonist or antagonist?
“Alcohol is an indirect GABA agonist,” says Koob. GABA is the major inhibitory neurotransmitter in the brain, and GABA-like drugs are used to suppress spasms. Alcohol is believed to mimic GABA’s effect in the brain, binding to GABA receptors and inhibiting neuronal signaling.
Does alcohol deplete dopamine?
Alcohol use overloads the brain with dopamine, while also reducing the brain’s dopamine receptors in the process. When you first quit drinking, the lack of dopamine and diminished receptors can lead to feelings of sadness and hopelessness.
Does alcohol release dopamine?
