A researcher is using a strong magnet to create images of the blood flow in participants' brains as they complete decision-making tasks. The researcher is using ____________ to examine the brain's activity.
A)functional magnetic resonance imaging (fMRI)
B)positron emission tomography (PET)
C)electroencephalography (EEG)
D)transcranial magnetic stimulation (TMS)

Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) is used to measure and map the brain's activity by detecting changes in blood flow. When an area of the brain is more active, it consumes more oxygen, and to meet this increased demand, blood flow to that area increases. The fMRI can detect these changes, making it a powerful tool for imaging brain activity, including during decision-making tasks.
