V. Ramachandran desribes a bit of this in his book "The Emerging Mind".
The Penfield-Homunculus is not an exact replica of the body, because the face is located directly besides the hand. Therefore, when a person is missing one arm, the neurons can cross-link, that is when they don't receive any input they form connections with the nearest area - in this case the face.
This is why people with phantom limbs sometimes feel their missing hand when their face is touched, another example is that when the face is stimulated with ice cubes, they feel as if the phantom limb got cold.
