Using internet and other resources, research a current theory of causes of SIDS

To what extent is there a single "cause" of SIDS? Alternatively, consider the proposition that SIDS is merely a term of convenience used by pathologists when they are unable to determine the cause and that the term "unascertained" is a preferable, and more honest, approach.

Write a discussion post of at least 150 words based on the following prompt (answer both questions):

• Think of an activity you did today. Using what you learned in this module, describe at least five different parts of your brain and how they were involved in that activity.
• If you were a psychologist or neuroscientist interested in learning more about one of those brain parts, what methods could you use to determine more about the brain?
