Alcohol affects both “excitatory” neurotransmitters and “inhibitory” neurotransmitters. An example of an excitatory neurotransmitter is glutamate, which would normally increase brain activity and energy levels. Alcohol suppresses the release of glutamate, resulting in a slowdown along your brain’s highways.
What neurotransmitters are affected by alcohol?
Some of the neurological pathways known to be affected by alcohol consumption include the dopaminergic, serotoninergic, γ-amino butyric acid (GABA) and glutamate pathways.
