[PopSci] Science Tricks the Brain into Experiencing Having Three Arms

post #1 of 19

If you’ve ever wondered what it might be like to have an extra arm, a team of Swedish researchers would love to show you. Scientists at the medical university Karolinska Institutet were wondering the same thing, so they set up an experiment to find out. It turns out it’s possible to experience having three arms at the same time...

But in a series of simple--if somewhat crude--experiments, the Karolinska team was able to trick the brain into accepting a third arm as the body’s own. The team took 154 healthy individuals and placed their arms on the table next to a third, realistic-looking prosthetic right arm.

The entire time I read this, I kept comparing it to using DaemonTools on my brain.

Awesome....I think it would've been cooler had they filled the prosthetic with some kind of red fluid and then stabbed it just to see how one patient would react.

Would have been awesome. Maybe a bit like terminator 2: "i want you to listen to me very carefully."

Wasn't there a similar study some years back where scientists tricked our brain into confusing our body with that of a nearby mannequin? They then poked the mannequin to see how the person would react, and sure enough, the people felt themselves being poked when they really weren't. My memory of the study is absurdly vague, hopefully someone can fill in the details.

Am I the only one thinking about the perverted uses of this?
