Salk Institute Scientists hope to borrow strategy from simpler animals to repair damaged spinal cord nerves in humans Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is—while many animals have this ability, humans don't. But new research from the Salk Institute suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits. Such a feat could eventually lead to therapies for the...

Clue To Regrowing Nerve Cells Identified
2013-11-07 12:54:44

Washington University School of Medicine Researchers at Washington University School of Medicine in St. Louis have identified a chain reaction that triggers the regrowth of some damaged nerve cell branches, a discovery that one day may help improve treatments for nerve injuries that can cause loss of sensation or paralysis. The scientists also showed that nerve cells in the brain and spinal cord are missing a link in this chain reaction. The link, a protein called HDAC5, may help...

First of its kind, brain-inspired device looks toward highly efficient and fast parallel computing It doesn't take a Watson to realize that even the world's best supercomputers are staggeringly inefficient and energy-intensive machines. Our brains have upwards of 86 billion neurons, connected by synapses that not only complete myriad logic circuits; they continuously adapt to stimuli, strengthening some connections while weakening others. We call that process learning, and it enables...

Neuroscientists Discover New ‘Mini-neural Computer’ In The Brain
2013-10-31 07:35:43

University of North Carolina at Chapel Hill School of Medicine Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now researchers at UNC have shown that dendrites actively process information, multiplying the brain’s computing power. The finding could help researchers better understand neurological disorders. Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now...

Dendrites In Brain Act As Mini-Neural Computers

Brett Smith for redOrbit.com - Your Universe Online Initially thought of as a simple means of sending signals in the brain, new research, published on Sunday in the journal Nature, has revealed that the dendrite sections of neurons are capable of processing information. "Suddenly, it's as if the processing power of the brain is much greater than we had originally thought," said study author Spencer Smith, an assistant professor in the UNC School of Medicine. "Imagine you're reverse...

Understanding How Neurons Get Wired

University of Arizona Two different versions of the same signaling protein tell a nerve cell which end is which, UA researchers have discovered. The findings could help improve therapies for spinal injuries and neurodegenerative diseases. University of Arizona scientists have discovered an unknown mechanism that establishes polarity in developing nerve cells. Understanding how nerve cells make connections is an important step in developing cures for nerve damage resulting from spinal...

Researchers of the Department of Biosystems Science and Engineering of ETH Zurich were able to measure the speed of neuronal signal conduction along segments of single axons in neuronal cultures by using a high-resolution electrical method. The bioengineers are now searching for plausible explanations for the large conduction speed variations. To write this little piece of text, the brain sends commands to arms and fingers to tap on the keyboard. Neuronal cells with their cable-like...

Slowdowns in the transport and delivery of nutrients, proteins and signaling molecules within nerve cells may contribute to the development of the neurodegenerative disorder ALS, according to researchers at the University of Illinois at Chicago College of Medicine. The researchers showed how a genetic mutation often associated with inherited ALS caused delays in the transport of these important molecules along the long axons of neurons. Their findings were published in the online...

“The Sodium Theory Revisited” reveals newest developments in nerve function research. UNITED KINGDOM (PRWEB) May 24, 2013 The sodium theory has been elegantly proposed by A.L. Hodkin, A.F. Huxley and B. Katz in the early 1950s, after their experiments on Plymouth squids, to account for the role of sodium and potassium ions in nerve functions. Since then, the electrophysiological techniques and the data acquisition techniques have known amazing developments. In The Sodium Theory...

Researchers at Georgetown University Medical Center (GUMC) have found what they say is evidence that veterans who suffer from "Gulf War Illness" have physical changes in their brains not seen in unaffected individuals. Brain scans of 31 veterans with the illness, compared to 20 control subjects, revealed anomalies in the bundles of nerve fibers that connect brain areas involved in the processing and perception of pain and fatigue. The discovery, published online March 20 in PLOS ONE, could...
