Brain Scans (Psychology)

Match each brain scans to the technology being used to create the image.

• electrodes measure brain waves

• PET

• magnetic properties of blood w/ oxygen

• MRI

• radioactive tracer on glucose

• fMRI

• electromagnetic waves & H2O molecules

• EEG

• 2D X-ray slices compiled into 3D image

• CT

Categorize each brain scan based on whether it shows static structures or dynamic function.

Groups:

(a) Static Structures

,

(b) Dynamic Function

• fMRI

• CT

• MRI

• EEG

• PET

Creates compilation images of X-ray slices that show the density of brain structures

• CT

• MRI

• PET

• fMRI

• EEG

Uses changes in electrically charged molecules in a magnetic field to form images of the brain.

• CT

• MRI

• PET

• fMRI

• EEG

Most similar to a CT scan, but creates more detailed images.

• CT

• MRI

• PET

• fMRI

• EEG

Tracks changes in blood flow and oxygen levels to indicate neural activity.

• CT

• MRI

• PET

• fMRI

• EEG

Records the brain’s electrical waves to detect abnormal activity.

• CT

• MRI

• PET

• fMRI

• EEG

Use radioactive tags to show which brain areas become active when someone performs a task.

• CT

• MRI

• PET

• fMRI

• EEG

Most useful for identifying location & dimension of tumors. Select TWO.

• CT

• MRI

• PET

• fMRI

• EEG

Most useful for mapping active areas of the brain or determining how diseases such as Alzheimer's diminish brain function. Select TWO.

• CT

• MRI

• PET

• fMRI

• EEG
