Pros of fMRI |
USes Subtraction method Can See differences in brain base don blood flow |
|
|
Cons of fMRI |
Poor Resolution Need to overlay fMR image on top of mr IMAGE |
|
|
PROS OF DIFFUSION TENSOR Imaging |
More Static form of imaging View Pathways Can detect degenration of axons, distortion of fibers and damage to fibers |
|
|
Pros of MRI |
High resolution No exposure to Radiation |
|
|
Cons of MRI |
Relatively poor temporal resolution |
|
|
Pros of PET Scan |
Can develop specific radioactive tracers to measure different kinds of metabolic activity |
|
|
Cons of PET Scan |
Costly Exposure to radiation Low Resolution Indirect measurement of neural activity -Infers neural activity based on assumptions of blood flow increases in area where neural activity increases |
|
|
Pros of CT Scan |
Creates 3D images Allows you to see ventricles and major fissures of brain |
|
|
Cons of CT |
Low Resolution Cannot discriminate between gray and white matter |
|
|
Pros of X-ray Imaging Techniques |
Cheap Straightforward |
|
|
Cons of X-ray Imaging Techniques |
Poor resolution Exposure to radiation |
|
|
Pros of Magnetoencephalography (MEG) |
High Resolution |
|
|
Process of MEG |
Records megnetic fields of neurons Permits 3D localization of the cell groups generating the magnetic field |
|
|
Cons of MEG |
Expensive |
|
|
Pros of EEG & ERP |
Excellent Temporal Resolution |
|
|
Cons of EEG ERP |
Poor Spatial Resolution |
|
|
Pros of TMS |
Noninvasive Can be used to map functional regions of the brain |
|
|
Cause & Effect of TMS |
TMS acts as a cause and effect process. Has the ability to manipulate |
