Quote:Experiments were performed at Stockholm's Karolinska Institutet medical university, in which a highly-realistic prosthetic right arm was placed on a table beside human subjects' own arms, so they could see all three. Scientists then simultaneously touched both the prosthetic arm and the subjects' own right arms with a small brush, at the same location on both arms.
"What happens then is that a conflict arises in the brain concerning which of the right hands belongs to the participant's body," said Arvid Guterstam, one of the scientists conducting the research. "What one could expect is that only one of the hands is experienced as one's own, presumably the real arm. But what we found, surprisingly, is that the brain solves this conflict by accepting both right hands as part of the body image, and the subjects experience having an extra third arm."
So far, he has reportedly been able to "transfer" subjects' selves into bodies of a different sex, age, or size, but not into inanimate objects. In one ongoing robotics-related project, however, researchers are trying to determine if someone's perceived body can be shrunk down to the size of a Barbie doll.
Do they hope to accomplish here? Strange experiments.
