Abstract: Tactile perception is typically deteriorated during action – i.e., tactile suppression. Although significant advances towards its understanding have been made, its exact neural mechanism and functional relevance, are still under intense scientific debate. Given the pervasive action-related deterioration of tactual function, this project aims to comprehensively investigate tactile processing for naturalistic action (e.g., reach-to-grasp actions, haptic search). This goal will be studied for both external tactile stimuli touching our skin, and for those intrinsic action-related tactile consequences. Further, this project will use interoceptive breathing with the goal to improve, for the first time, what is felt when we move. Therefore, this is the first attempt to characterizethe integration of tactile information during naturalistic goal-directed action, across three experimental questions: 1) How is tactile information processed during action? 2) Which are the cognitively-driven tactile priorities for the execution of a meaningful action? and 3) Can we teach our body to improve our actions? The ambitious goal is to demonstrate that mastering non-action/action (through breathing training) contributes to reverse the traditionally-observed deterioration for movement-related tactile information. Sensorimotor integration will be investigated by using state-of-the-art techniques including behaviour (e.g., signal detection, sensory priors, and unexpected sensory events), advanced movement kinematics, electroencephalography (EEG), augmented virtual reality (VR), and breathing training. The results will enhance our understanding of disease from sensorimotor abnormalities and will provide significant insights into tactile function for applied health. This work has outstanding potential for the development of innovative technological devices for neuroprosthetics-based rehabilitation and of reliable bodily-aware tools and solutions for well-being (e.g., wearable technology).
