 You may have heard of Phantom Limb syndrome before. This passage from an article started me thinking about what things are present in the market that
we feel but don't in fact see, adding to the chance of our ache and
ruin. Or alternately, what is present in markets that helps to guide us,
no matter our deficiencies?

"The woman was born with only three fingers on her right hand and had the hand amputated after a car accident when she was aged 18. She later began to feel that her missing limb was still present and developed a "phantom" hand.

"But here's the interesting thing," Paul McGeoch at the University of California, San Diego, told New Scientist. "Her phantom hand didn't have three digits, it had five."

However RN's phantom thumb and index finger were less than half the usual length and were painful.

Dr McGeoch and Professor V.S Ramachandran used a mirror box which reflected the woman's left hand to make it look like she had a pair of limbs.

After two weeks of training RN was able to extend the short fingers on her phantom limb, which relieved her pain.

McGeoch said the study indicates that there is a hardwired representation in the brain of what the body should look like, regardless of how it actually appears in real life. It showed more about the balance between the external and innate representations of a limb, he said."
