• no other case of that type of brain damage has ever been seen

• it was the earliest recorded case of brain damage affecting personality

• doctors can compare Gage's brain scans to other patients

This type of brain imaging 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 & radio waves, and a computer to give researchers a picture of a slice of the brain from any angle.

Hint: shows structure but NOT function.

• MRI

• PET

• EEG

• fMRI
