B)PET
C)fMRI
D)CAT

Question

Quizplus · Accepted Answer

The researcher is most likely using functional magnetic resonance imaging (fMRI) to track changes in blood oxygen levels in the brain when participants view and imagine a scene. fMRI uses strong magnets to measure changes in blood flow and oxygenation levels, allowing researchers to identify which brain regions are more active during different tasks. EEG (A) measures electrical activity in the brain, PET (B) measures brain metabolism, and CAT (D) is a type of X-ray that produces detailed images of internal structures in the body.
