How visual experience impacts the internal and external spatial mapping of sensorimotor functions

Abstract Tactile perception and motor production share the use of internally- and externally-defined coordinates. In order to examine how visual experience affects the internal/external coding of space for touch and movement, early blind (EB) and sighted controls (SC) took part in two experiments. I...
