We know the shape of our own body and its configuration in space. Of course, you feel that your body shape is stable in daily life. However, some simple tricks can induce illusions that make you feel that your arm is elongated or as if a dummy rubber hand is your own hand. These illusions suggest that our brain constantly updates the representation of own body by integrating sensory information received via sense of body movement, touch, vision and hearing. Understanding the neural mechanisms behind the construction and maintenance of our body representation will lead to future information communication technology that can convey our bodily sensations.
