Parsons and her colleagues are doing a study comparing differences in brain activity levels between patients with schizophrenia and controls with no psychological disorders. Their hypothesis requires a high level of detail and good detection of differences over time. Which of the following is the best brain imaging technique to use?
A) computerized tomography (CT) scan
B) functional magnetic resonance imaging (fMRI)
C) magnetic resonance imaging (MRI)
D) positron emission tomography (PET)

Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) is the best choice for this study because it provides both a high level of detail in brain structure and can detect changes in brain activity over time by measuring blood flow, which is an indicator of neural activity. This makes it particularly useful for comparing brain activity levels between different groups.
