Dani has a seizure disorder, and her neurologist wants to determine the overall pattern of brain activity to help determine the locus of her seizures. She has a variety of electrodes placed all around her skull and lies still as a series of recordings are made. Dani is most likely undergoing which type of test?
A) an electroencephalogram or EEG
B) transcranial magnetic recording
C) an MRI
D) a PET scan

Question

Quizplus · Accepted Answer

An electroencephalogram (EEG) is a test that measures electrical activity in the brain. It is commonly used to diagnose epilepsy and determine the locus of seizures. The electrodes placed on Dani's skull suggest that she is undergoing an EEG. Transcranial magnetic recording and PET scans are not typically used to diagnose seizure disorders, and while an MRI may be used in some cases, the electrodes used in Dani's test indicate that she is undergoing an EEG specifically.
