Constantly Testing

The video explores the phenomenon of phantom pain, its historical context, and various theories explaining it. Initially thought to be caused by peripheral nerve damage, newer studies suggest a brain-centric view where the brain's internal model of the body creates a mismatch, leading to phantom sensations. The brain imposes its perception on the world, continuously testing hypotheses about the body's state.
