Body ownership is the ongoing feeling that our body and body parts belong to us, and are related to us in a different way than things in the external world. This sense of body ownership may seem trivial to us, yet our brain needs to connect sensory inputs (e.g., touch, pain, and visual information), internal inputs (from our body's internal milieu), and higher cognitive inputs like memories of our body in different events to generate the sense of ownership. For instance, hand ownership is generated by the visual input we get from our eyes that tracks its location, sensory input on its posture (known as proprioception), and the touch of the table that we lean on, as well as our sense of familiarity with our hand and our memories of the hand along our personal history.
