Brain Imaging Tecnhiques

fMRI, MRI & EEG are examples of

• brain scans

• non-invasive methods

• imaging techniques

• invasive methods

Psychologists are interested in investigating...

• structure

• density

• function

• levels of alertness

MRI stands for

• magnet resounding imaging

• magnetic resounding investigation

• magnetic resonance investigation

• magnetic resonance imaging

What does Electroencephalography do?

• Track anatomical structure

• Examines neurons to track electrical signals in the brain

• Detect lesions early

• Make images of the brain

This machine is used to record the electrical activity of large portions of the brain. 

• MRI
• CAT
• PET
• electroencephalograph

This image uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of brain tissue.

• MRI

• PET

• EEG

• CAT scan

This scan is best suited for looking at soft tissues such as ligaments and tendons, the brain, and many of the internal organs.

• MRI

• PET

• X-Ray

• EEG

This is a technique for measuring and mapping brain activity that is noninvasive and safe.

• EEG

• X-Ray

• fMRI

• CAT scan

The attractions of this image have made it popular for imaging normal brain function. Over the last decade it has provided new insight to the investigation of how memories are formed, language, pain, learning and emotion.

• MRI

• fMRI

• EEG

• X-Ray

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

• EEG

• PET

• MRI
