A researcher wants to obtain a "movie" of changes in the activity of the brain using images from different time periods.Which of these would be the best choice for this researcher?
A)electroencephalography (EEG)
B)computerized axial tomography (CT)
C)positron-emission tomography (PET)
D)functional magnetic resonance imaging (fMRI)

Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) is the best choice for obtaining a "movie" of changes in the activity of the brain using images from different time periods. fMRI measures changes in blood oxygenation in response to neural activity, allowing for the visualization of changes in brain activity over time. EEG measures electrical activity in the brain, CT produces detailed images but does not show activity, and PET measures metabolic activity rather than changes in activity over time.
