Two techniques that are now widely used provide an indirect measure of more localized brain activity, as compared to electrical scalp recordings.These two techniques are
A)positron emission tomography (PET)and functional magnetic resonance imaging (fMRI)
B)functional magnetic resonance imaging (fMRI)and parallel distributed processing (PDP)
C)parallel distributed processing (PDP)and positron emission tomography (PET)
D)functional magnetic resonance imaging (fMRI)and event-related potential (ERP)

Question

Quizplus · Accepted Answer

Positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) are both widely used techniques that provide an indirect measure of localized brain activity. PET measures changes in blood flow and metabolism, while fMRI measures changes in blood oxygenation levels. Both techniques provide high spatial resolution and can localize brain activity to specific regions. The other answer choices do not accurately describe two widely used techniques for measuring localized brain activity.
