Delta Epsilon fraternity sponsors a Beer Fest every October, where party-goers consume large amounts of alcohol. At the neurotransmitter level, what is happening to the party-goers?

The sensitivity of receptor sites for gamma-aminobutyric acid (GABA) is increased in the party-goers due to the alcohol consumed by them.

Explanation:

The alcohol which is consumed by the party-goers tends to disturb the balance achieved by the brain between the senses that are existent within the human body. It stimulates certain receptors to become more sensitive than others and causes the brain to receive excessive signals from those receptors alone. This causes disturbances in the functioning of neural circuits and makes the person behave abnormally.
