Ramachandran's Mirror experiment

Here in this experiment Dr. Ramachandran talks about how a person who has lost a limb can not visually and khiaesthetically confirm their movement and sensation. The brain becomes stuck and is no longer connected to or influenced with the outside of that arms environment. So first he placed an mirror perpendicularly to the persons chest at the shoulder of the missing arm. The mirror creates a symmetrical reflection of their other existing arm making the person feel like they have an arm in the place of the missing arm. The person was after then asked to focus on the image of the good limb in place of the missing limb for quite a while. Afterward the person would be asked to move the good limb and the image of the good limb in place of the missing limb. The brain will be little by little tricked and the brain would substitute the healthy neurological pattern of the communication with the good limb in place of the missing limb. This type of experiment could be used to ease the sensation of the pain of the missing limb through therapy.
