1. Methods of Studying the Brain
Mr. Koch
AP Psychology
Forest Lake High School

3. Clinical Observation Study effects of accidents/brain damage
(oldest way of studying)
Strokes
Traumatic Injury
Tumor
Lesion

4. Clinical Observation
Phineas
Gage
Frontal lobotomy

5. Electrical Stimulation
Note effect of weak electrical currents on behavior Can be used on humans or animals

7. Electroencephalograph (EEG)
Electrodes measure electrical waves sweeping across surface of the brain

8. Brain Scans
CAT (or CT Scan)
MRI
PET
fMRI
TMS

9. CAT (CT) Scan Computerized Axial Tomography
Cross-section X-ray pictures of the brain Can reveal brain damage

10. MRI Magnetic Resonance Imaging
Aligns atoms in brain, then disorients them, measures detectable signals as they move back into place
Gives detailed picture of soft tissues

11. PET Scan Positron Emission Tomography

12. PET Scan

13. fMRI Functional MRI

14. TMS Transcranial Magnetic Stimulation
Newer method – has been used in treatment of depression
