'It's all in the mind', takes on a whole new meaning with research revealing that phantom limbs can be taught to do physiologically impossible tasks."The brain's sense of how to implement this movement depended on the brain reconstructing the limb in order to let this movement happen according to the normal principles of physics,"
I can imagine my hand move, I can feel it move - but its not moving. I can imagine a hand coming out from my chest and I can feel it as if it is thre, but I just can't see it with my eyes
There is another part of the brain that gives us the sense of ownership over the various parts of our bodies (separate from the mapping of the world above). In rare cases after damage this ownership module can lose its input from a paralyzed limb and instead create the illusion of ownership over an imaginary limb (a supernumerary phantom limb). People with this condition feel as if they have an extra limb – they can see it and feel it, and even scratch themselves with it.
What researcher have learned is that the brain can be tricked by mixing up the tactile and visual input into placing the sense of self somewhere other than where the body is actually located.
The researchers believe this implies that our body image must obey Newton's laws, and we may make adjustments to ensure they continue to do that even when the mind is making the rules for itself.
