Our results show dramatic distortions of hand shape, which were highly consistent across participants," Longo said in a prepared statement.
This trend "mirrors similar gradients of decreasing tactile acuity," the authors pointed out, and the results seem to back up models of the human body, such as the somatosensory homunculus, constructed from the amount of sensory cortex dedicated to various body parts. In these models the hands and face are disproportionately large in comparison to most of the body. But Longo and Haggard are still not sure why the brain has such a distorted perception of our hand proportions.

Denne studien kan også delvis forklare de pasientene som konstant føler at en smertefull kroppsdel er hoven (selv om den fysisk ikke er det)?
