Question

g much attention has been paid to the role of dopamine in drug reward. (a) what are the two primary mechanisms by which addictive drugs can elicit increased dopaminergic transmission in the nucleus accumbens? (b) is such an increase in dopaminergic transmission equally important for all addictive drugs? explain your answer.

Answer 1

The primary mechanism by which addictive drugs can elicit increased dopaminergic transmission in the nucleus accumbens is by causing a pleasurable surge for the drug.

All addictive drugs, including alcohol, opioids, and cocaine, cause a pleasurable surge of the neurotransmitter dopamine in a part of the brain called the basal ganglia; neurotransmitters are chemicals that send messages between nerve cells. Every substance has generally different effects on the brain.

For a long time, it was thought that the euphoria we feel right after using narcotics was caused by the release of dopamine. Dopamine is likely a reinforcing agent for taking more of the drug, according to more recent studies. It increases a drug addict's desire for the substance.
