How do the receptors in your skin respond to the touch of silk or a drop of rain? Our touch system plays an essential role in how we discriminate between different surfaces and objects, which allows us to interact effortlessly with our surroundings. We readily distinguish between a vast range of solid textures, from fine hairs to polished surfaces, as well as between different liquids, via complex percepts like wetness, stickiness, and oiliness. This is enabled by highly precise input from different types of mechanoreceptors in the skin that respond in specific ways to touch. If this system is interrupted, interacting with the world becomes problematic. In somatosensory disease or body injury, such as peripheral neuropathy or amputation, the consequences are dramatic on the quality of life. The current project aims to understand how touch is encoded in humans: from fundamental signals in single touch receptors in the skin, to the generation and perception of complex sensations. These insights will help in elucidating the causes and treating the symptoms of somatosensory disorders. Furthermore, applying the knowledge for the provision of realistic sensory feedback in prosthetics represents a great advancement in terms of individual and social usage of a prosthetic device, allowing far more naturalistic interactions and increased embodiment. Overall, Project ARTTOUCH has two main objectives: (i) to use electrical stimulation in human nerves to activate a single nerve fiber and produce artificial sensations that can be quantified perceptually and through using neuroimaging and (ii) to investigate how touch of complex surfaces is encoded and perceived, such as when interacting with different textures and liquids. These results provide exquisite insights into the human touch system and how it works in everyday life, where we easily feel differences in textures, surfaces, and even small drops of rain. The end aim of the project is to provide information on how these precise sensations are generated to then re-inject this input artificially, via electrical stimulation into nerves in amputees with a prosthetic device, to provide real-time, sensory feedback during prosthetic touch.
