Answer:
B. Leslie had more dopamine receptors than other participants.
Explanation:
Ritalin (methylphenidate hydrochloride) is a central nervous system stimulant drug used to treat Attention Deficit Hyperactivity Disorder (ADHD). Ritalin also serves to treat narcolepsy, a sleep disorder that is characterized by excessive daytime sleepiness, even if the person has slept well at night.
Ritalin increases the activity of certain areas of the brain that are poorly active, promoting increased attention and concentration, and decreasing impulsive behavior. In narcolepsy, Ritalin works by relieving sleep throughout the day. The mechanism of action of Ritalin is the same as that of amphetamines and other stimulants, ie it increases the concentration and reuse of neurotransmitters such as dopamine and norepinephrine in the brain. For this reason, people with more dopamine receptors in their brain (such as Leslie) when taking ritalin feel pleasant feelings.
<u>The moment when I felt confident about a decision made by me:</u>
It was during my 12th standard, I was about to decide if I have pursued Engineering or Medicine. Many of my relatives suggested me to go for Medicine, as they thought it is the only profession where you could make more money and be successful.
My passion is to become an engineer. I was too confident and thus opted for Engineering, though my parents were unhappy with the decision. But as soon as they saw my progress in studies, as well as my project, works they understood me very well and supported a lot. At last, after my graduation, I was happy that I had gone through all the negatives and got a good job.
