When you brush your teeth, the toothbrush may actually become part of your arm – at least as far as your brain is concerned. That's the conclusion of a study showing perceptions of arm length change after people handle a mechanical tool.
The brain might also readily incorporate cyborg additions – a cyborg arm or other body part – into its body schema, says Farné, "and possibly new body parts differing in shape and/or number, for example four arms."
The brain maintains a physical map of the body, with different areas in charge of different body parts. Researchers have suggested that when we use tools, our brains incorporate them into this map.
To test the idea, Alessandro Farné of the University of Claude Bernard in Lyon, France, and colleagues attached a mechanical grabber to the arms of 14 volunteers. The modified subjects then used the grabber to pick up out-of-reach objects.
