Parietal Cortex Involved in Proprioception

Posted Jul 26 2010 4:05am
Recent research published in Current Biology reports on proprioception. Subjects had to determine information regarding touch AND location. The posterior parietal cortex was the brain area responsible to determine touch AND location. When magnetic stimulation was used to impair the subject's parietal cortex, the perception of touch or location alone was not decreased. It was only when the subject's were asked to define touch AND location, that the results were impaired.
This information could play a key role in determining how children develop a map of the body in space.
