Extreme unicycling looks exactly how it sounds, extreme. It takes an already complex task in unicycling and makes it more difficult by riding on the edge of a mountain and in rough terrain. Since it is so complex, it involves many different brain structures to be activated to provide proper balance, visual information, planning of the movement, and the actual locomotion to go from point A to point B. An example of how the unicyclist uses all of these together is they use their vision by scanning the environment to formulate their plan of movement, which then requires the locomotion initiation to enact the movement plan, and then balance adjustments are constantly being made to remain upright and continue with the movement. As you can see, there is a great deal of overlap between these categories, which is a key point to understand with this schema map. The four main categories listed make up the primary aspects of extreme unicycling: locomotion, balance, movement planning, and vision.
