_____ detects blood flow to brain regions, indicating heightened neural activity.
A)Functional magnetic resonance imaging (fMRI)
B)Positron emission tomography (PET)
C)Computerized axial tomography (CAT)
D)Electroencephalogram (EEG)

Question

Quizplus · Accepted Answer

fMRI is a non-invasive imaging technique that measures changes in blood oxygenation levels in the brain. This allows researchers to detect increased neural activity in specific regions of the brain, as blood flow increases to those areas. PET scanning can also be used to detect blood flow in the brain, but it involves the injection of a radioactive tracer and is more invasive than fMRI. CAT scanning and EEG do not provide information on blood flow to the brain.
