2. With respect to cell death, active cell death is called
necrosis
regeneration
apoptosis
degeneration
|
3. The main principle that governs the effects of experience on neural development is simple:
use it or lose it
live and let live
familiarity breeds contempt
the best of friends must part
|
4. An ischemic is
an area of damage produced by a stroke
a stroke
the area of regeneration following a stroke
an island of normal brain tissue in an area of the brain damaged by ischemia
|
5. One reason why the implantation of fetal substantia nigra precursor cells has not been used more frequently in the treatment of Parkinson's disease is that
tests with a monkey model have been negative
the acquisition of fetal brain tissue for transplantation raises complex ethical issues
the transplants are often rejected
tests with a rat model have been negative

6. Which of the following brain-imaging procedures allows metabolically active neural areas to be located by injecting radioactive 2-DG?
PET
CT
EEG
Structural MRI
|
7. Structure is to function as
fMRI is to PET
CAT is to MRI
MRI is to PET
PET is to CAT
|
8. The ability of the nervous system to be modified is known as
Plasticity
Regeneration
Collateral sprouting
Denervation supersensitivity
|
9. ______ are chemical that enhance development and survival in neurons.
teratogens
endorphines
glucocorticoids
neurotrophins
|
10. Supersensitivity
includes both denervation and disuse
contributes to increased number of receptors and effectiveness of receptors
helps explain why normal behavior may be maintain despite substantial damage to axons
all of the above
