Interacting with the world

In this chapter, the extent to which actions and perceptions depend on each other is explored particularly for the visual system. Viewing the world through a mirror or a lens that displaces or inverts images provides examples of our ability to learn new sensorimotor consistencies. The use of sensory prostheses that replace one sensory modality with another, for example, visual by tactile stimuli or vestibular by tactile stimuli, provides examples of the capacity of our brains to learn about new sensorimotor relationships, often with surprising rapidity, even in an adult.
