Select Three Neuroimaging Techniques Outlined in the Textbook

Question

Examlex · Accepted Answer

The Answer is Student could select any three from the list below.
Computerized tomography (CT)scan: 3D image created using multiple X-rays.Benefit: Cheap,no issues with metal in the body.Drawback: Lower resolution than other techniques (e.g. ,MRI).
Magnetic resonance imaging (MRI): 3D image created by measuring how different areas of the brain absorb and release energy while in a magnetic field.Benefit: High-resolution.Drawback: Use of magnetics means individuals with metal embedded or surgically inserted into their bodies may not be able to be scanned or are at risk for injury.
Diffusion tensor imaging (DTI): measures white matter pathways in the brain.Benefit: White matter tends to be implicated in many diseases and disorders.Drawback: Doesn't image gray matter (cortex).
Electroencephalogram (EEG): Measures patterns of brain activity.Benefit: High temporal resolution-can indicate when brain activity is occurring.Drawback: Low spatial resolution-not very precise in determining where activity is originating.
Magnetoencephalography (MEG): Measures electrical activity associated with active neurons.Benefit: Better spatial resolution than EEGs and good temporal resolution (speed).Drawback: Although better than EEGs,still not very high spatial resolution (hard to pinpoint specific brain area).
Positron emission tomography (PET)scan: Measures activity in the brain by measuring levels of radioactive isotope (often glucose).Benefit: Allows researchers to see metabolic activity in the brain and measure involvement of specific receptors.Drawback: PET scans are very slow which means it is difficult to measure quick changes in brain activity.
Functional magnetic resonance imaging (fMRI): measures brain activity by detecting oxygen consumption in brain areas.Benefit: Allows for accurate measurements of specific active brain areas,easy to use,does not involve radioactivity.Drawback: Correlational,meaning causation cannot be derived from the results.
