A new study that uses a model of a hand has found that our brain’s representation of our body is out of sync with reality, a perception that could lead to distortions in body image and possibly a contributing factor to eating disorders such as anorexia. University College London scientists found that when participants put their left hand palm down under a board and asked to judge where certain landmarks were, the subjects perceived their fingers to be one-third shorter and hands to be two-thirds fatter than they actually were. The research, published in the journal Proceedings of the National Academy of Sciences, aimed to determine the process behind an ability called “position sense”, in which the brain knows where all parts of the body are in space, even with the eyes closed.
