Neuroimaging Techniques Quiz

What is the primary purpose of neuroimaging techniques in psychological research?

• To physically manipulate brain structures for experimental purposes

• To capture images of the brain and study its structure and function

• To measure a person’s level of intelligence

• To replace traditional methods of studying behaviour

Which of the following is a structural neuroimaging technique?

• PET

• fMRI

• CT

• EEG

What is the main difference between structural and functional neuroimaging techniques?

• Structural techniques show brain structure, while functional techniques show brain activity

• Functional techniques are used only for medical diagnoses

• Structural techniques expose participants to radiation, while functional techniques do not

• Functional techniques require surgical intervention

What does a CT scan primarily use to create images of the brain?

• Magnetic fields

• X-rays

• Glucose tracers

• Electrical impulses

Why might an MRI be preferred over a CT scan?

• MRI images are more detailed and can distinguish subtle changes in brain tissue

• MRI scans are less expensive than CT scans

• MRI scans use radioactive tracers for enhanced accuracy

• MRI is the only technique that provides information about brain function

What is the key feature of functional neuroimaging?

• It only provides black and white images

• It shows the brain in a resting state only

• It provides images of the brain while it is engaged in an activity

• It requires surgical implantation of electrodes

How does PET scan brain activity?

• By detecting glucose metabolism using a radioactive tracer

• By measuring electrical activity in the brain

• By tracking oxygen flow in the blood

• By using X-rays to identify neural connections

Which functional neuroimaging technique measures oxygen levels in blood flow to determine brain activity?

• CT

• MRI

• fMRI

• SPECT

What is an advantage of fMRI over PET?

• fMRI does not expose participants to radiation

• fMRI produces images that are less detailed but faster

• fMRI measures brain activity using glucose tracers

• fMRI is the only method that can show the brain’s structure

Which of the following is NOT a functional neuroimaging technique?

• PET

• MRI

• fMRI

• SPECT
