Episode description
Alcohol absorbs very rapidly and enters the bloodstream quickly, reaching all parts of the body. In the brain, alcohol binds to receptors for acetylcholine, serotonin, GABA, and the NMDA glutamate receptors.
This binding to multiple receptors has a profound effect on mood, memory, personality, alertness, and physical coordination. The most significant impact of alcohol in the brain is on the GABA receptors and the NMDA glutamate receptors. Glutamate is the most prevalent excitatory neurotransmitter in the brain.
