What is the role of the prefrontal cortex in the brain?

• It is responsible for processing visual information

• It controls the sense of taste

• It helps in controlling impulsive behaviors

• It regulates the production of dopamine

What is the function of dopamine in the brain?

• It helps in controlling impulsive behaviors

• It controls the sense of taste

• It regulates the production of insulin

• It is responsible for processing visual information

What did the researchers find in their study of 'teenage' mice fed high-fat foods?

• Mice on high-fat chow had reduced levels of dopamine in their prefrontal cortex

• Mice on high-fat chow had no impact on the levels of reelin in their prefrontal cortex

• Mice on high-fat chow had increased levels of reelin in their prefrontal cortex

• Mice on high-fat chow had roughly 35 percent less reelin in their prefrontal cortex

What is the impact of high-fat and high-sugar diets on adolescent brains?

• It can lead to increased physical fitness

• It has no impact on mental health

• It can lead to improved cognitive abilities

• It can lead to disturbing changes in mental health

What is the role of the prefrontal cortex in working memory?

• It is involved in reasoning and decision-making

• It is responsible for processing auditory information

• It regulates the sense of smell

• It controls the sense of touch

What did the researchers observe in the maze test with the mice?

• Mice eating a healthy diet did not prefer any one arm of the maze

• Mice eating a high-fat diet preferred one arm of the maze

• Mice eating a high-fat diet did not prefer any one arm of the maze

• Mice eating a healthy diet preferred one arm of the maze

What is the impact of dopamine on adolescent brains?

• Adolescents have no dopamine receptors in the brain

• Adolescents have the same number of dopamine receptors in the brain as adults

• Adolescents have fewer dopamine receptors in the brain than do adults

• Adolescents have more dopamine receptors in the brain than do adults

What is the impact of high-fat and high-sugar diets on the ability to resist junk food?

• It makes junk food easier to resist and improves teen health

• It has no impact on the ability to resist junk food

• It makes junk food harder to resist but has no impact on teen health

• It makes junk food both hard to resist and extra bad for teen health

What did the researchers find in their study of 'teenage' mice fed high-fat foods regarding working memory?

• Mice eating high-fat food had no impact on their performance in memory tests

• Mice eating high-fat food had improved performance in memory tests

• Mice eating high-fat food performed better on memory tests than did mice eating a normal diet

• Mice eating high-fat food performed worse on memory tests than did mice eating a normal diet
