How injured nerves grow themselves back

Unlike nerves of the spinal cord, the peripheral nerves that connect our limbs and organs to the central nervous system have an astonishing ability to regenerate themselves after injury. Now, a new report in the October 1st ...

A turning point for young neurons

During neural development, newborn neurons extend axons toward distant targets then form connections with other cells. This process depends on the growth cone, a dynamic structure at the growing axon tip of ...

Improving recovery from spinal cord injury

Once damaged, nerves in the spinal cord normally cannot grow back and the only drug approved for treating these injuries does not enable nerve regrowth. Publishing online this week in the Early Edition of the Proceedings of ...

Targeted molecules play only minor role in axon repair

Neuroscientists at the University of California, San Diego School of Medicine have found that removing three key inhibitory molecules from myelin - the insulating material that surrounds nerve cell fibers - does not significantly ...
