Corollary discharge/motion sickness

            This week during class I had also found the topic regarding corollary discharge very helpful regarding motion sickness. Many times I have attempted to read even a short piece of writing during a car ride, but my carsickness shows up shortly after. I have found sometimes though that I can read a short piece of writing during a car ride without feeling any symptoms of carsickness, yet other times I don’t even have to read much and the symptoms will appear shortly after. Also, my carsickness shows up only when reading, but doesn’t seem to show up when I’m doing some sort of puzzle. Because the nervous system experiences something that it had not expected, motion sickness arises; however, it would be interesting to find out why I only get motion sickness when concentrating on a book, but not on a puzzle. I also find it amusing how differently some individuals’ nervous systems respond to input signals regarding motion sickness. Just how others have mentioned, some individuals in my family have no issue with motion sickness, yet my mom and I get motion sickness very easily. This adds to the differences between humans because if we all responded to the same inputs the same way, humans would be that much similar. The phantom limb example used in class was also very interesting and it makes sense that one with an amputated limb would still feel it on their body despite the fact it is not there anymore and when they are able to visualize their amputated limb through a mirror, the symptoms of the syndrome decrease.
