The brain goes through many changes as we age. Select and examine a developmental phase and describe the status of the brain at the selected phase.

Before completing this discussion, be sure to review Chapter 4 of your text, and the REM Sleep video.  You may also find it helpful to explore the Eunice Kennedy Shriver National Institutes of Child Health and Human Development website from the recommended resources.

After examining the research inpresented in your required resources, please choose and complete one of the following discussion options:

Option A: The brain goes through many changes as we age. Select and examine a developmental phase (infancy, childhood, adolescence, adulthood and old age) and describe the status of the brain at the selected phase. How may this shape behavior?

Option B: Sleep patterns change as we age. Select and examine a developmental phase (infancy, childhood, adolescence, adulthood and old age) and provide a description of the sleep patterns at the selected phase. How does your selected phase compare to those of other developmental phases?

Your initial post must be at least 300 words and use a minimum of one scholarly source located in the Ashford University Library or on Google Scholar that is cited and referenced according to APA style, as outlined in the Ashford Writing Center.

Guided Response: Review several of your classmates’ posts. Provide a substantive response to at least two of your peers in a minimum of 200 words. Respond to a post that examines a developmental phase different from the one you selected and one that examines the same phase. Discuss the extent to which you agree or disagree with the content of each post. Be sure that you cite scientific evidence to support your views.
