Question

Quizplus · Accepted Answer

Positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) are the two techniques that allow researchers to visualize changes in brain activity over time. PET detects the changes in glucose metabolism in different areas of the brain, while fMRI detects changes in blood flow and oxygen utilization. Computerized tomography (CT) and magnetic resonance imaging (MRI) are structural imaging techniques that provide information about the brain's structure rather than brain activity.
