The consumption of glucose in active regions of the brain underlies the usefulness of a(n)
A) MRI.
B) brain lesion.
C) EEG.
D) PET scan.

Question

Quizplus · Accepted Answer

PET scans (Positron Emission Tomography) involve the injection of a radioactive form of glucose, which allows for the measurement of glucose consumption in active brain regions. This information can be used to understand brain activity during specific tasks or in response to different stimuli. MRI (A) and brain lesions (B) can provide structural information about the brain, while EEGs (C) measure electrical activity in the brain. However, none of these techniques directly measure glucose consumption.
