07 Ch 2 - Brain Imaging Techniques

The allows researchers to look at the activity of the surface of the brain through electrodes places on the scalp.

• EEG

• PET

• MRI

• fMRI

These are computer-aided x-rays of the brain that show a great deal of brain structure.

• CT scan

• MRI scan

• PET scan

• EEG

These use a magnetic field and a computer to give researchers a picture of a slice of the brain from any angle.

• MRI

• PET

• EEG

• fMRI

These allow researchers to look at the activity of the brain during various mental tasks by producing a "video."

• fMRI

• MRI

• PET

• EEG

These use radioactive sugar injected into the bloodstream to tract the activity of brain cells, which is enhanced and color-coded by a computer.

• PET

• MRI

• fMRI

• EEG

This technology is good for sleep research.

• EEG

• MRI

• fMRI

• CT scan

This technology is the LEAST helpful to look at the brain's tissues.

• EEG

• PET

• fMRI

• MRI

This technology does NOT require a high degree of radiation exposure.

• MRI

• CT scan

• X-ray

This technology is most useful to show structural damage from a brain tumor or brain damage.

• CT scan

• EEG

• X-ray

• fMRI

This technology cannot be used on someone with metal in their body.

• MRI

• EEG

• CT scan

• X-ray
