Summary:
- This article discusses how the brain's representation of a lost limb changes after amputation.
- Researchers used brain imaging to map the brain activity of people who had lost a limb, and found that the area of the brain that used to control the missing limb becomes "rewired" to process sensations from other parts of the body.
- This brain plasticity, or the ability to adapt and change, is an important discovery that could lead to better prosthetic devices and treatments for phantom limb pain experienced by amputees.
