How do agonists affect the neurotransmission
Webdemonstration that alcohol can affect the function of specific neurotransmit-ters1 (Lovinger et al. 1989). Studies of neurotransmitters and the receptors to which they bind have provided data on both the structure and the mecha-nism of action of these molecules as well as clues to their role in behavior. However, the function of individual

Agonists are chemicals that mimic a neurotransmitter at the receptor site and, thus, strengthen its effects. An antagonist, on the other hand, blocks or impedes the normal activity of a neurotransmitter at the receptor. Agonist and antagonist drugs are prescribed …
