The correct answer would be option B, fMRI.
Francois is studying the effects of concussion on memory. He wants to observe the brain activity of victims as they perform memory tasks in real time. fMRI is the brain imaging method which is most appropriate for this study.
Explanation:
fMRI stands for Functional Magnetic Resonance Imaging. This is the brain imaging method which measures the activities of the brain. These activities are measured by detecting the changes in the brain associated with the blood flow.
According to this method, cerebral blood flow and neuronal activation in the brain are coupled. It also relies on the fact that when a part of the brain is in use, the flow of blood in that area also increases.
So when Francois wants to study the effects of concussion on memory, the best method to support his study is to use the method of Functional Magnetic Resonance Imaging.
