Module 4 Discussion
You can grow new brain cells
Discussions are an opportunity for you to practice clearly and effectively communicating your ideas, interact with and respectfully challenge your peers, and support your writing with examples and scholarly resources.
It's time to get introduced to the concepts of the nervous system and neuroplasticity. Neurogenesis occurs during development and can also occur in response to environmental stimuli. Unfortunately, neurogenesis in the central nervous system of humans is limited in its ability to recover after damage. Recent research indicates that more extensive neurogenesis may be possible in the central nervous system.
Watch the TEDTalk to introduce yourself to important concepts within this module, and then post your reaction. Remember this is due before your discussions, on Wednesday of each week. The purpose of this is to help scaffold your learning so that you are introduced to module topics in the first assignment and then complete the learning quiz to help you become more familiar with the language and concepts. You'll then be fully prepared to participate in a meaningful way within the discussion for the week, and be able to show off the things you've learned in your assignment due every Sunday.
Successfully completing this activity demonstrates achievement of Module Outcomes 3 and 4.

Now, answer the following:
Identify something you learned about the brain and neurons that you can use in your daily life to understand or work with others.
Given that brain damage seems to induce adult neurogenesis, what adaptive role, if any, might these new cells be playing? In your answer, describe the concept of "cognitive reserve" and the potential role of adult neurogenesis in recovery following CNS damage.
Based on your writing above, what would you say to someone who tells you that physical activity protects one from the development of Alzheimer's Disease. What would be your response to that person? Use examples from your life or current events and/or scholarly evidence to support your argument.
Consult Discussion Criteria and the Discussion Posting Guide for information about writing your discussion posts. This is a “post first” discussion forum. You must submit your initial post before you can view other students’ posts.
Remember to properly cite and reference your sources in APA format!
This discussion will be graded using the discussion board rubric. Please review this rubric, located on the Rubrics page within the Start Here module of the course, prior to beginning your work to ensure your participation meets the criteria in place for this discussion. All discussions combined are worth 35% of your final course grade.
Keep the following points in mind when working in the discussion forums:
Postings should display originality in thought and insightful synthesis.
Postings should demonstrate understanding of key concepts.
Responses should be original and stimulate discussion.
