Today in Scientific Studies Sure To Make You Go ‘Huh’ we bring you the latest news from researchers at the Karolinska Institutet, who have succeeded in inducing phantom limb sensations that can make people feel like they have a third arm. After just a few minutes being exposed to an illusion — having their own arm, which they can’t see be stroked with a paintbrush while the air in front of them is stroked similarly — participants in the experiment were so invested in their new limb that their stress levels jumped when the fake hand was threatened with a very real knife.
