Leslie participated in a research study in which she was given a dose of ritalin and reported to researchers that she found the effects pleasurable. other participants given the same dose reported the effects were unpleasant. what did researchers find when they compared dopamine receptors in her brain to those who found the drug unpleasant?

Leslie had more dopamine receptors than other participants.

Explanation:

For starters, Ritalin is a drug used to treat ADHD that works by altering certain substances already present in the brain, which is why this drug is basically a stimulant. This drug is also used to treat narcolepsy. It basically helps the patient with focusing and controlling behavior problems. Since Ritalin promotes the reuse of dopamine and stimulates it, if people experience pleasurable effects, it means that their levels of dopamine is higher than usual, which is Leslie's case, hence this drug would feel potentially stronger in comparison to other people with regular levels of dopamine.
