Quote:

I have heard of people who have amputated limbs and how they can still feel pain from these phantom appendages.



I actually have heard of somebody who after surgery was still reaching for her penis even though it was not exactly where it used to be. Old habits die hard.

True stories:

One patient had gnawing sensations in his phantom arm until he discovered his discarded limb was being devoured by maggots. Another felt pleasant sensations in her phantom foot every time she had sexual intercourse.

It's a great documentary to watch, if you are interested in brainy things. It's called "Secrets of the Mind", from Nova.
