Gaze-centered spatial coding of touch on a hand-held tool
Abstract
Humans possess the remarkable ability to project tactile sensations outside their body and onto a hand-held tool. Despite nearly a century of research, the computations underlying this projection have not been adequately addressed. We combined computational modeling and psychophysics to demonstrate that egocentric tactile remapping underlies tool-based sensory projection. These findings provide the first characterization of the computations underlying the spatial projection of touch on external objects, highlighting the incredible versatility of the sensorimotor system.
