Question

Quizplus · Accepted Answer

An fMRI measures changes in a patient's blood oxygen level, which can provide information on brain activity and function. As different areas of the brain become active, they require more oxygen, leading to changes in blood flow and oxygenation that can be detected by fMRI. This allows researchers to map which areas of the brain are involved in different tasks or processes, and can be used to diagnose neurological and psychiatric disorders.
