Alcohol does this by interacting with the receptors on the receiving cells in these pathways. Alcohol affects various centers in the brain, both higher and lower order. The centers are not equally affected by the same BAC -- the higher-order centers are more sensitive than the lower-order centers. As the BAC increases, more and more centers of the brain are affected. The order in which alcohol affects the various brain centers is as follows: Cerebral cortex.

Most of the alcohol gets absorbed through the stomach and small intestine. Once in the bloodstream, alcohol can cross the blood-brain barrier and affect the brain.
