| CT scan | A series of X-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brain structure |
| Pet Scan | A visual display of brain activity that detects where a raidioactive form of glucose goes while the brain preforms a given task |
| MRI | A technique that uses magnetic field and radio waves to produce computer-generated images of soft tissue |
