Which method of studying the living brain involves injecting a slightly radioactive solution into the blood and measuring the amount of radiation absorbed by brain cells?
A) SET scan
B) MRI scan
C) PET scan
D) EEG

Question

Quizplus · Accepted Answer

The method described in the question is the PET scan (Positron Emission Tomography), which involves injecting a slightly radioactive solution (usually FDG) into the blood and measuring the amount of radiation absorbed by brain cells. This allows researchers to analyze the activity of different areas of the brain, as areas that are more active will absorb more of the radioactive solution. The other options listed, SET scan, MRI scan, and EEG, use different methods of analyzing the brain such as measuring electrical activity or creating images based on magnetic fields.
