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 Frontal lobotomy Phineas Gage

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
