I sensi della vita

In this episode we discover our five senses: we try to understand how they work, what things they can reveal to us and what are beyond their reach, and how they are different from those of some animals. In fact, our senses give us a portrait of the world that would be profoundly different if, for example, we explored it with the senses of another species. We also discover how touch and pain perception work and how this changes depending on the area of the body that is involved.
