Question

Quizplus · Accepted Answer

PET stands for positron emission tomography and is a brain imaging technique that detects the uptake of certain molecules in the brain, such as glucose or oxygen.

Answer: B
 EEG stands for electroencephalography and is a brain imaging technique that detects changes in the electrical activity of the brain over time, often measured using electrodes placed on the scalp. It is also able to detect changes in blood flow in the brain.

Answer: A
 fMRI stands for functional magnetic resonance imaging and is a brain imaging technique that measures changes in blood flow in the brain to infer neural activity. It does not record the brain's electrical activity from the scalp.
