How Phantom Limb Tricks Us
Our brains play many tricks on us. Phantom limb, a condition where amputees feel vivid sensations in a limb that is no longer there, is one of the more mysterious. First documented in the 16th century by French military surgeon Ambroise Paré among soldiers who had lost limbs in battle, its name wasn’t coined until a few hundred years later by American Civil War surgeon and renowned neurologist Silas Weir Mitchell, who wrote a popular fictional a…
Groundbreaking Discovery: The Brain Retains a "Mental Map" of Body Parts Following Amputation
After a serious accident or the contraction of a particular disease, the only way to intervene the body of a patient is sometimes the amputation of one or more members. But if you actually lose a member, the brain does not forget it. Furthermore, he would even keep a mental card of lost members. But the brain is a great and particularly complex muscle that we still paint to understand completely. This phenomenon of feeling pain, discomfort or si…
In the brain, a lost limb is never really gone - TPR: The Public's Radio
Even years after an arm is amputated, the brain maintains a detailed map of the limb and tries to interact with this phantom appendage. The post In the brain, a lost limb is never really gone appeared first on TPR: The Public's Radio.
An imaging study of amputated persons in the arms reveals that the brain map of the body remains remarkably stable even after years. This calls into question the long-standing idea that this brain map is completely reorganised after the loss of a limb to compensate for missing parts. This discovery could have important implications for the development of prosthetics and pain treatments for "phantom limbs." The primary somatosensorial cortex (S1)…
Phantom limb study reveals brain retains map of lost limb
NIH researchers found that the brain’s control centre for a lost limb persists long after amputation, challenging theories of cortical remapping. This insight into phantom limb syndrome could inform future neuroprosthetic and pain treatments A new NIH study shows that the brain keeps a map of a lost limb long after amputation. By examining participants with phantom limb sensations, researchers found that the primary motor cortex remains active, …
