Oh yeah, it's fascinating stuff. Actually it happens that people have a really well-defined physical self image. Phantom limb syndrome is the most obvious
case - if someone loses an arm, they'll still "feel" like they have an arm.More intriguing, I've read about a case where someone had no arms
from at leastr a very young age if not birth, later received prosthetics, and then complained that the prosthetics were not
the same length as their arms.
Then there's people who have a limb but feel like it isn't theirs and want it removed. Brain scans on some of these people have shown that the limb
doesn't trip certain self-recognition areas of the brain. (Or something like that; I forget exactly what failed to activate.)
