Small electrodes are pasted onto Miranda's scalp and are connected by wire to a machine that translates the electrical energy from her brain into wavy lines on a moving piece of paper.From this description,it is evident that Miranda's brain is being studied through the use of
A)a computerized tomography (CT)scan.
B)functional magnetic resonance imaging (fMRI).
C)diffusion tensor imaging (DTI).
D)an electroencephalogram (EEG).

Question

Quizplus · Accepted Answer

The use of small electrodes to translate the electrical activity of Miranda's brain into wavy lines on a moving piece of paper is characteristic of an electroencephalogram (EEG), making choice D the best option. This is a non-invasive method of measuring the electrical activity of the brain, and it is often used in the diagnosis of various neurological conditions, as well as in research to study brain function. Choices A, B, and C all refer to other imaging techniques that are not based on the use of electrodes to detect brain activity.
