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)computed 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 can capture changes in the blood flow and oxygen levels in the brain, which are linked to neuron activity. This allows for the identification of specific regions of the brain that are active during different tasks or stimuli. EEG does not provide images of brain activity, CT is not sensitive to changes in brain activity, and PET requires the injection of a radioactive tracer.
