Keiju, being the first successful human recipient of a rodent replacement arm, it is to be expected that you, and specifically in this case, your nervous tissue, will have trouble collecting, transmitting and translating data from the little mouse receptors. If the problem persists, however, it is a early warning sign that your body may be rejecting the transplant. Please come back out of that maze so we can do further tests. We have cheese.
Why is cheese so delicious?
