Small metal disks are pasted onto Miranda's scalp and they 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 CT scan.
B) functional magnetic resonance imaging.
C) a microelectrode.
D) an electroencephalogram.

Question

Quizplus · Accepted Answer

The use of small metal disks connected to a machine that translates electrical energy from the brain into wavy lines on a moving piece of paper describes an electroencephalogram (EEG). EEGs are commonly used to study brain activity and can be used to diagnose conditions such as epilepsy, sleep disorders, and brain injuries. Options A and B refer to imaging methods that use magnetic fields and radio waves, while option C involves the use of a small electrode to record electrical activity from a specific neuron.
