Question 1

Neuropsychology

Answer 1

Study of the relationships between brain function and behavior in humans

Question 2

Magnetoencephalogram (MEG)

Answer 2

Magnetic potentials recorded from detectors placed outside the skull

Question 3

Computed tomography (CT)

Answer 3

X-ray technique that produces a static three-dimensional image (called a CT scan) of the brain in cross section

Question 4

Magnetic resonance imaging (MRI)

Answer 4

Technique that produces a static three-dimensional brain image by passing a strong magnetic field through the brain, followed by a radio wave, then measuring a radiofrequency signal emitted from hydrogen atoms

Question 5

Diffusion tensor imaging (DTI)

Answer 5

Magnetic resonance imaging method that can image fiber pathways in the brain by detecting the directional movements of water molecules

Question 6

Magnetic resonance spectroscopy (MRS)

Answer 6

Magnetic resonance imaging method that uses the hydrogen proton signal to determine the concentration of brain metabolites

Question 7

Functional magnetic resonance imaging (fMRI)

Answer 7

Magnetic resonance imaging technique that measures brain activity indirectly by detecting changes associated with the ratio of oxygenated and deoxygenated blood; often used to measure cerebral blood flow during cognitive testing or resting

Question 8

Resting-state fMRI (rs-fMRI)

Answer 8

Magnetic resonance imaging method that measures changes in oxygenation levels when the individual is resting (not engaged in a specific task)
