1. Brain Imaging Techniques
The Case of Phineas Gage - lesioning

2. Electroencephalogram (EEG)
Shows brain waves (levels of consciousness, activity levels)
No structure or function

3. Magnetic Resonance Imaging (MRI)
Shows structure of brain
Does not show function or areas of activity

5. CAT Scan (computerized axial tomography)
X-ray cross-sections of brain
Structure but no function

6. PET Scan (positron emission tomography)
Inject patient w/substance that traces oxygen/blood flow/glucose
Shows activity in areas of the brain (indicates function)
Does not show structure

7. Sept. 12th Finish brain imaging Note quiz Parts of brain activity
HW: just the reading on the calendar (no video)

8. fMRI (functional MRI)
Combines MRI & PET scan
Shows both structure & function

9. MEG Scan (Magnetoencephalography)
Maps brain activity through magnetic fields
Shows brain activity & function, non-invasive, fast
Often used to find the location of origin for seizures
