Regrowing damaged nerves hinges on shutting down key genes

Neurons in the brain and spinal cord don't grow back after injury, unlike those in the rest of the body. Cut your finger, and you'll probably be back to using it in days or weeks; slice through your spinal cord, and you likely ...

Building a better brain-computer interface

Brain-computer interfaces, or BCIs, represent relatively recent advances in neurotechnology that allow computer systems to interact directly with human or animal brains. This technology is particularly promising for use in ...

Implant helps paralysed man walk again

Five years after he was paralysed in a snowmobile accident, a man in the US has learned to walk again aided by an electrical implant, in a potential breakthrough for spinal injury sufferers.

Paralyzed mice with spinal cord injury made to walk again

Most people with spinal cord injury are paralyzed from the injury site down, even when the cord isn't completely severed. Why don't the spared portions of the spinal cord keep working? Researchers at Boston Children's Hospital ...

Researchers repair acute spinal cord injury in monkeys

Spinal cord injuries are among the most severe and difficult-to-treat medical conditions, usually resulting in permanent disability including loss of muscle function, sensation and autonomic functions. Medical research is ...

Scientists find key protein for spinal cord repair

A freshwater zebrafish costs less than two bucks at the pet store, but it can do something priceless: Its spinal cord can heal completely after being severed, a paralyzing and often fatal injury for humans.

Spinal cord injury

Spinal cord injuries cause myelopathy or damage to white matter or myelinated fiber tracts that carry signals to and from the brain. It also damages gray matter in the central part of the cord, causing segmental losses of interneurons and motorneurons. Spinal cord injury can occur from many causes, including:
