Abstract

What do you do when you are playing in the park on a hot day and your parents offer you an ice cream? Most probably, you go running to them, keep your eyes on the delicious ice cream cone, and reach out to take it from them. Although this feels like the most natural thing to do, it requires the fine coordination of your different sense organs and movements. You need your eyes (sense of vision) to look at the ice cream, your arms to reach out (motor system), and your hands (sense of touch) to hold it firmly. It seems obvious that in order to be able to reach out and grasp something, we need to first be able to see it and know where it is. Surprisingly, this is not always true.
