Question 13

When he was younger, your parents had Phil see a psychiatrist because they were worried that his risk-taking behaviours would put him in danger. The doctor prescribed a medication that functions to change the balance of neurotransmitters in the brain.

It appears that the medication is having the desired effect on the _________ lobe, along with an undesired effect on the _______ lobe

a) occipital; temporal
b) temporal; parietal
c) frontal; occipital
