The concept of set points seems intriguing, almost impossible for my to fathom.  I understand the general concept, but like you said in class, if you found out how they are set and/or change you could win the nobel prize.  What I can't fathom is where would these set points even take place.  In cells, in the nervous system, in the brain, or in the muscles.  What makes them the set point rise when one has a fever and how is such a medicine like tylenol supposed to help against fevers(i.e. lower the set point back to normal?) And it seems like there could be hundreds of these set points in ones body to keep it at homeostastis.  

A few times throughout my life I have been awoken during sleep, i am conscious, but my body does not respond to my desired action, similar to a state of paralyzation.  Why is it that my brain is awake, but my body is not.  Why are the corollarry discharges not able to move my muscles when my brain is sending signals for movement.  There is no splice in my spinal cord, so is it just simply my brain is conscious and my body is alseep, and how can one be awake and the other not.  It is not like when u sleep on ur arm and it falls asleep from lack of blood flow.  My body is stuck.
