My dad sent me this article on how scientists have manipulated the brain's perceptions of its physical self. It's tripping me out.
"In one experiment, the team fitted the head of a mannequin with two cameras connected to two small screens placed in front of volunteers' eyes, so that they had the same view as the mannequin. When the mannequin's camera eyes and a participant's head were directed downwards, the participant saw the mannequin's body where the person would normally have seen their own body. The researchers created the illusion of body-swapping by touching the stomach of both the mannequin and the volunteer with sticks. The person saw the mannequin's stomach being touched while feeling (but not seeing) a similar sensation on their own stomach. As a result, the person developed a strong belief that the mannequin's body was actually their own."
This is very weird, sci-fi stuff. And yet, it's also fascinating how the mind can be tricked.
