The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. In a study from Sweden’s Karolinska Institutet, a team of neuroscientists now reports a perceptual illusion of having an invisible body, and show that the feeling of invisibility changes our physical stress response in challenging social situations.
The history of literature features many well-known narrations of invisibility and its effect on the human mind, such as the myth of Gyges’ ring in Plato’s dialogue The Republic and the science fiction novel The Invisible Man by H.G. Wells. Recent advances in materials science have shown that invisibility cloaking of large-scale objects, such as a human body, might be possible in the not-so-distant future; however, it remains unknown how invisibility would affect our brain and body perception.
