9 Cards in this Set
- Front
- Back
|
CT scan
|
computerized tomography scan; computer enhanced Xray of brain STRUCTURE; radioactive; shows slices; cheaper than MRIs
|
|
|
MRIs
|
magnetic resonance imaging scan; uses magnetic fields and radio wavves to map out brain STRUCTURE; much better resolution than CT scans, 3D but more expensive; not radioactive!
|
|
|
PET scan
|
positron emission tomography scans; use radioactive markers (glucose) to map chemical activity in brain, studies FUNCTION;
|
|
|
fMRI
|
functional magnetic resonance imaging; monitor blood flow and oxygen consumption; map activity and FUNCTION in the brain but also STRUCTURE; not as good resolution as MRI
|
|
|
TMS
|
transcranial magnetic stimulation; uses magnets to excite neurons in certain parts of the brain to learn about function in the brain; noninvasive
|
|
|
lesioning
|
destroying a piece of the brain to study its function. may damage something on the way down. hard to interpret
|
|
|
electrical stimulation of the brain (ESB)
|
sending a weak electric current into a brain structure to stimulate it; invasive
|
|
|
studying brain damaged peopel
|
cannot manipulate brain
confounding variables |
|
|
aspiration
|
sucking out parts of the brain like a vacuum?
