B)electroencephalogram
C)functional MRI
D)electromyogram

Question

Quizplus · Accepted Answer

A functional MRI (fMRI) is a technique used to measure brain activity by detecting changes associated with blood flow. During cognitive tasks, areas of the brain that are involved in the task require more oxygen and nutrients, increasing blood flow to those areas. This increased blood flow can be detected by an fMRI and used to provide evidence of what brain processes are involved in the task. Microtomography is a technique used to create detailed images of very small objects or animals, and an electroencephalogram (EEG) measures electrical activity in the brain but does not provide the spatial resolution of an fMRI. An electromyogram (EMG) measures electrical activity in muscles and is not directly related to cognitive processing.
