The Importance of the Brain Stem: Exploring Questions and Debating Answers

We are on the home stretch, and it is more important than ever to stay committed and on-course! You can do this!
The brain stem is an interesting subject as we often take its ability for granted. Out of all the things that the body can do, the most important things are those that we are most unaware. Think about breathing. How often do you stop and focus on your breathing? If you are living in this current world of always being on the go, the chances are that you go day to day without ever truly realizing that you are breathing. It just happens.
What about heart rate control? Yes, some of it is determined via catecholamines (fancy chemicals) and the sinoatrial node (natural pacemaker of the heart), along with the help of the parasympathetic and sympathetic nervous systems. But the brain stem is involved! What about the sleep/wake cycle, auditory and visual reflex response, body temperature control and overall consciousness? Yes, the brain stem is in play with all these functions. It is so vital that injury to this area has serious consequences and is often fatal!
Informally and based upon what you now understand about the brain and cranial nerves, think about the following questions posed. Discuss and, most importantly, debate the “why” of one question that interests you most. As this is a discussion, the goal is to debate freely with your peers and to have the opportunity to explore and analyze, not only your chosen question, but also the thoughts of your classmates. You might find that you end on a topic below that is far removed from your original choice. That is ok and encouraged!
Why do some individuals with cranial nerve disorders experience autonomic dysfunction?
Why is the brain’s reward system so important for motivation and addiction?
Why do certain brain disorders, such as Parkinson’s or Alzheimer’s progress over time?
Why do some believe that certain types of music or meditation can alter brain function?
Why do some scientists believe that consciousness is an emergent property of the brain versus others who believe that it is a separate, non-physical entity?
Why do some researchers believe that neuromodulation can be used to treat cranial nerve disorders?
Why do some people struggle with impulse control?
Why is it important to assess cranial nerve function?
