Question

Which statement is true about dopamine?

A. Dopamine discourages healthy behavior.
B. Drug-addicted brains become used to tolerating higher levels of dopamine.
C. Dopamine stimulates displeasure and lack of memory.
D. Damage from addiction can be reversed.

Answer 1

B. The release of dopamine as a result of drug use tricks the brain into believing the drug is good for the body.

Dopamine is the brain's "pleasure" neurotransmitter. It is released during normal pleasurable activities: sex, food, having fun, etc.

Most illicit drugs feel pleasurable because they increase the release of dopamine throughout the brain's pleasure centers.

This, falsely, feels good and tells the mind and body that it's good for you since it's pleasurable.

Step-by-step explanation:

Answer 2

The answer is B. Drug-addicted brains become used to tolerating higher levels of dopamine. Dopamine release in the nucleus accumbens is linked with pleasure. Drug use cause a powerful surge of dopamine in the nucleus accumbens. Due to this surge, drug misuse is more likely to occur.
