The human brain consists of approximately one hundred billion nerve cells. Each of these cells needs to connect to specific other cells during the brain's development in order to form a fully functional organism. Yet how does a nerve cell know where it should grow and which cells to contact? Scientists of the Max Planck Institute of Neurobiology in Martinsried have now shown that growing nerve cells realize when they've reached their target area in the fly brain thanks to the interaction of...

New research using a mouse model of the motor neuron disease spinal muscular atrophy (SMA) reveals an abnormality in the way that sensory information is relayed to motor neurons in the spinal cord. Importantly, this disruption in communication occurs very early in disease progression and precedes the neuronal death and muscle weakness that are the hallmark of the disease. The study, published by Cell Press in the February 10 issue of the journal Neuron, suggests that therapeutic strategies...

Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered. The findings are published in the Feb. 6 advance online edition of the journal Nature Biotechnology. Nerve...

This finding has particular importance because several neurodevelopmental disorders have recently been linked to genetic mutations in the complex developmental cascade containing Erk and its sister proteins. Researchers at the University of North Carolina at Chapel Hill have pinpointed a crucial function for a key player in the development of the nervous system. They found that this player "“ a protein called Erk "“ is necessary for nerve fibers to be wrapped with an insulating...

New research from the University of North Carolina at Chapel Hill School of Medicine describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses. New research from the University of North Carolina at Chapel Hill School of Medicine describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses. The findings appear online Jan. 27, 2011 in the journal Neuron. Our hard-wired nerve fibers or...

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 issue of Cell, a Cell Press publication, offers new insight into how that healing process works. "We know a lot about how various cell types differentiate during development, but after a serious injury like an amputation, nerves must re-grow," said Allison Lloyd of...

Researchers at Stanford University were able to use light to induce normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins. The new approach allows scientists to more accurately reproduce muscle firing order, making it a valuable research tool. The investigators, from Stanford's Schools of Medicine and of Engineering, also believe this technique could someday spawn practical applications, from...

For these patients, immunotherapy can quickly improve symptoms A new Mayo Clinic study found that nerve inflammation may cause the pain, numbness and weakness following surgical procedures that is known as postsurgical neuropathy. The development of postsurgical neuropathies is typically attributed to compression or stretching of nerves during surgery. This new research shows that, in some cases, the neuropathy is actually caused by the immune system attacking the nerves and is...

Researchers from UCI, UCSD and Harvard deleted a cell growth inhibitor called PTEN Researchers for the first time have induced robust regeneration of nerve connections that control voluntary movement after spinal cord injury, showing the potential for new therapeutic approaches to paralysis and other motor function impairments. In a study on rodents, the UC Irvine, UC San Diego and Harvard University team achieved this breakthrough by turning back the developmental clock in a molecular...

BOSTON, Aug. 8 /PRNewswire-USNewswire/ -- Researchers for the first time have induced robust regeneration of nerve tissue connections in injured adult spinal cord sites that control voluntary movement. These findings provide hope that it may be possible to design therapies for paralysis and other impairments of motor function arising from spinal cord injury. In rodent studies, the Children's Hospital Boston, UC Irvine, and UC San Diego team made this breakthrough by turning back the...
