____ are used to study cerebral glucose metabolism.

Question

Quizplus · Accepted Answer

PET scans (Positron Emission Tomography) are the most common imaging technique used to study cerebral glucose metabolism. It involves injecting a radioactive tracer into the bloodstream which emits positrons, and these positrons annihilate with electrons in the brain tissue, releasing gamma rays that can be detected by a scanner. This allows researchers to map the activity and metabolism of brain regions associated with specific cognitive behaviors. EEGs (Electroencephalography) measure electrical activity in the brain and are often used to investigate brain function and diagnose certain conditions such as epilepsy. CT scans (Computed Tomography) and MRIs (Magnetic Resonance Imaging) are imaging techniques that generate detailed images of the structures of the brain, but they do not provide information about brain function or metabolism.
