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.

Answer:
diffusion tensor imaging (DTI)
Explanation:
Diffusion tensor imaging (DTI) is a recently developed technique that makes use of magnetic resonance imaging (MRI) to analyze the nerve cells anatomy and the neuronal network that is found in the brain. This technique, an improved version of conventional MRI, was introduced for the first time in 1994 by Peter Joel Basser, who specializes in Healthcare Management, Quantitative Imaging, Brain Imaging and Neuroplasticity.
Answer:
Scientists concluded that fossils must show evidence of bipedal locomotion instead of just bigger brain sizes to be considered as a hominids.
Explanation:
They further stated that the notion that was previously believed that man became bipedal due to the enlargement of his brain was certainly false. Lucy had small brains, and yet she could stand erect. Furthermore, it was concluded that man would have split from his ancestors (ape) as far back as 15 million years ago because Lucy was very primitive.
The answer is B
