✨ Alert: A new NIH study upends what we thought we knew about the brain’s adaptability after limb loss.
In a first-of-its-kind study, researchers conducted MRI scans before and up to five years after arm amputation—revealing that the brain’s map of the missing limb remains stable over time, even without the limb present .
This discovery challenges the long-held belief that the brain undergoes large-scale reorganization (plasticity) following amputation. Instead, it shows that the brain holds onto the body, maintaining a consistent representation of the lost limb .
Why this matters for prosthetic care:
• Empowers neuroprosthetic and BCI (brain–computer interface) design to build on these persistent brain maps.
• Suggests that rehabilitation approaches relying on cortical remapping may need a rethink .
At Northeast Orthotics & Prosthetics, we’re energized by this evolution in understanding. It reinforces our dedication to designing prosthetic solutions that connect seamlessly with the brain, honoring the body’s own blueprint.
