Question

Quizplus · Accepted Answer

Of the options given, fMRI is the best choice for investigating brain activation during quick decision-making in stressful circumstances. fMRI measures changes in blood flow and oxygen levels in the brain, which can indicate which areas of the brain are being activated during a particular task. EEG measures electrical activity in the brain, and is more appropriate for investigating brain activity during sleep or while the brain is at rest. Electrocardiography measures electrical activity of the heart, and is not related to brain activation. Electroconvulsive therapy is a therapeutic technique, not a neuroimaging technique, and involves the use of electrical currents to treat mood disorders.
