Discussion 1

Neurogenesis, the growth and regrowth of neurons, occurs during development and can also occur in response to environmental stimuli. Unfortunately, neurogenesis in the central nervous system of humans is limited in the brain’sability to recover after damage. Recent research indicates that more extensive neurogenesis may be possible in the central nervous system through the use of stem cells. Discuss the possibilities for, as well as the ethical implications of, this line of research and ultimately treatment for disorders that damage the central nervous system.

Discussion 2

What does amnesia tell us about the neurological process underlying memory? Does Amnesia research help to advance our knowledge of learning and memory? If so, explain.
