If it talks like hand…

My hands are small I know
But they’re not yours, they are my own
But they’re not yours, they are my own – Hands, Jewel

Are they Jewel, are they!?

What they were cut off and attached to someone else’s limbs???

Hmmm…?

Okay, okay, ethical concerns of organ theft aside, apparently your mind is too stupid (or too smart!) to tell the difference between your hands and transplant hands.

A transplant patient’s brain scans showed exactly the same reactions expected from a non-amputee when his new hands were electronically stimulated. The same neural pathways that should have been used 35-years ealier, before he lost his hand, appeared to have been re-coopted successfully to manipulate and sense with the new appendage. (Unfortunately pre-transplant scan data was not taken so they can’t be sure that these pathways were the exact same ones this person was using for their hand, but its similar enough to be convincing).
