It is almost impossible to imagine a form of life without the ability to feel – sensation. The sensory system in humans has been studied for centuries, starting from Aristotle’s concept of the common sense, up to now when the discovery of new sensory receptors was made. A neuroscientist with Armenian origins Prof. Ardem Patapoutian and his colleague Prof. David Julius, were awarded the Nobel Prize in Physiology or Medicine in 2021 for an astonishing work: the discovery of receptors for temperature and touch.
