CPGs and Set Points
I think that I am starting to understand the concept of CPGs better. The example that I found very interesting was the CPG for signature. In the past, whenever I tried writing my signature with my left hand I noticed that, although it was messy, it did share many similarities with the signature written by my dominant right hand. It makes sense that this occurrence is due to the fact that there is a CPG that controls signature.
This week when we were talking about reafferent loops I found the internal set point for weight very interesting. I am a bit confused by this example. How does this set point exist? If a person eats more food that he or she normally eats then what does the body do with the extra calories in order to keep this person at his or his weight set point? Does this set point prevent tiny daily fluctuations in weight or does it prevent a person from losing or gaining a substantial amount of weight ? I am just a bit confused about this set point’s purpose and how it actually functions.
