C) paid adult donors. 
D) genetic engineering in the laboratory. 
A) nonhuman species. 
B) human embryos. 
C) paid adult donors. 
D) genetic engineering in the laboratory. B

Question 2

To what extent is the brain capable of continued development during adulthood? Distinguish between neuroplasticity and neurogenesis. Discuss the potential implications of these processes for the treatment of disorders of the nervous system. Identify at least one controversial issue in the application of neuroplasticity to the treatment of disorders.

Accepted Answer

The answer should contain the following elements:
The brain undergoes substantial development during adulthood. The interconnections between neurons become more complex throughout life, and new neurons are created in certain parts of the brain during adulthood.
Neuroplasticity-the process whereby the brain continually reorganizes itself.
Neurogenesis-the creation of new neurons during adulthood.
Treatment of nervous system disorders-stem cells may be used in the treatment of Parkinson's disease and spinal cord injuries. This work is controversial, however, because the main source of stem cells is human embryos. It is possible, though, that stem cells may be used from adult sources like bone marrow.
