Libby's physician refers her to a medical center in order to have the biochemical activity in her brain analyzed.She is given an injection of a glucose-like substance containing a radioactive element and then she lies with her head in a scanner.The technique being used is:
A)positron-emission tomography.
B)functional magnetic resonance imaging.
C)microelectrode recording.
D)an electroencephalogram.

Question

Quizplus · Accepted Answer

The use of a glucose-like substance containing a radioactive element and a scanner for analyzing biochemical activity in the brain is a technique called positron-emission tomography (PET). Option B (functional magnetic resonance imaging) uses magnetic fields to measure changes in blood flow, while option C (microelectrode recording) involves inserting tiny electrodes directly into the brain to record neural activity. Option D (electroencephalogram) measures electrical activity in the brain through electrodes placed on the scalp, but does not involve the use of any radioactive substances.
