Awareness of voluntary action, rather than body ownership, improves motor control

Abstract Awareness of the body is essential for accurate motor control. However, how this awareness influences motor control is poorly understood. The awareness of the body includes awareness of visible body parts as one’s own (sense of body ownership) and awareness of voluntary actions over that vi...

description	Abstract Awareness of the body is essential for accurate motor control. However, how this awareness influences motor control is poorly understood.
