Scientists succeed in making the spinal cord transparent

(Medical Xpress) -- In the event of the spinal cord injury, the long nerve cell filaments, the axons, may become severed. For quite some time now, scientists have been investigating whether these axons can be stimulated to ...

Signaling cascade that repairs damaged nerve cells characterized

Through a study of roundworm nerve cells with severed axons, researchers at Nagoya University showed that a signaling cascade that normally functions in promoting the phagocytosis of apoptotic cells also acts in inducing ...

When the brain's wiring breaks

Among all the bad things that can happen to the brain when it is severely jolted – in a car accident, for example – one of the most common and worrisome is axon damage. Axons are the long stalks that grow out of the bodies ...

Untangling the complex puzzle of optic nerve regeneration

The optic nerve is vital for vision—damage to this critical structure can lead to severe and irreversible loss of vision. Fengfeng Bei, PhD, a principal investigator in the Department of Neurosurgery at Brigham and Women's ...

Turn left! How myosin-Va helps direct neuron growth

Researchers at the RIKEN Brain Science Institute in Japan have discovered a protein complex that helps direct the growth of axons—the parts of neurons that make up our nerves, connecting our senses and muscles to the brain ...

Discovery helps explain what guides neurons to connect

It's a wonder of nature - and a darned good thing - that amid many billions of similar cells in the brain and spinal cord, neurons can extend their tendrillous axons to exactly the right place to form connections. Otherwise ...

New approach to spinal cord and brain injury research

Many an injury will heal, but the damaged spinal cord is notoriously recalcitrant. There's new hope on the horizon, though. A team of researchers led by the University of South Carolina's Jeff Twiss just reported an innate ...
