Name and describe three of the technologies used in neuropsychology to study the brain
What will be an ideal response?
Computerized tomography (CT) scans can give computer-enhanced three-dimensional X-ray images of the brain.
With positron emission tomography (PET), clinicians inject radioactive markers into a person's bloodstream and
then trace them through the brain as the person engages in certain cognitive tasks. Functional magnetic resonance
imaging (fMRI) can detect changes in the rate of metabolism, or energy consumption, in smaller areas of the brain.
With fMRI, researchers can precisely identify the specific parts of the brain that become more active as people
process different types of information.
