Electroencephalograph
Refers to EEG waves associated with a PARTICULAR EVENT or
TASK AVERAGED over a LARGE NUMBER OF TRIALS
ERP
It ia one methods of cognitive neuroscience that allow for the OBSERVATION of LARGE ABNORMALITIES of the
BRAIN, such as DAMAGE RESULTING FROM STROKES and TUMORS Examples CT: computerized axial tomography
MRI: magnetic resonance imaging
Static Imaging Techniques
It is one of the example of static imaging techniques that has a STRONG MAGNETIC FIELD is PASSED through the BRAIN of a patient and a ROTATING SCANNER DETECTs VARIOUS PATTERNS of ELECTROMAGNETIC
CHANGES in the molecules of the brain
MRI: magnetic resonance imaging
One of methods in cognitive neuroscience that RELIES on CHANGES that take place within the brain as a
RESULT of INCREASED CONSUMPTION of GLUCOSE or OXYGEN in ACTIVE AREAS of the BRAIN
Examples: PET, fMRI
Metabolic Imaging
What is the function of PET: Positron Emission Tomography?
Increased glucose consumption in active brain areas
What is the function of fMRI: Functional Magnetic Resonance Imaging?
Increased oxygen consumption in active brain areas
Is the OUTER LAYER of the cerebral hemispheres that PROCESS SNESORY INFORMATION, THINKING and PLANNING
