I'm glad that we started to discuss the nervous system in detail this week. The functions of the brain often trump the workings of the overall nervous system, but we have to remember that the nervous system is what connects our brain to our body. I appreciated the methods of interpreting the nervous system as boxes within boxes, interpreting inputs and outputs. Sometimes it is difficult to see the overall picture if we cloud our minds with extensive names and specific functions. However, I'm still interested in learning more about the specific biological aspects of the nervous system. The point in class that I found most interesting this week was that the nervous system can produce outputs without any inputs. This is difficult for me to understand because my education always focused on responses to stimuli. I think it's helpful to mention specific examples in order to fully understand the workings of the nervous system, which was done in class. I still don't think I fully understand outputs generating inputs, since the thought is so counterintuitive. Again, the examples are appreciated. I'm looking forward to learning more about the nervous system and how it enables us to function as human beings.
