1
New cards
Electroencephalograph (EEG)
Machine used to record the electrical activity of large portions of the brain
2
New cards
Computerized Axial Tomography (CAT)
A moving ring passes x-ray beams around the head; shows structure of the brain
3
New cards
Position Emission Topography (PET)
Imaging technique used to see which brain areas are being activated while peforming tasks; shows the activity levels of the brain; inject slightly radioactive solution
4
New cards
Magnetic Resonance Imaging (MRI)
Imaging technique used to study brain structure and activity; passes radio frequencies through the brain; effective at revealing small injuries and abnormalities
5
New cards
Functional Magnetic Resonance Imaging (fMRI)
Shows the structure/ function of the brain and activity levels of different areas; unlike the MRI, does not require passing radio frequencies through the brain
