Provided by Michael Dimitriou, Umea University Stretch sensors in our muscles participate in reflexes that serve the subconscious control of posture and movement. According to a new study published in the Journal of Neuroscience, these sensors respond weakly to muscle stretch caused by one's voluntary action, and most strongly to stretch that is imposed by external forces. The ability to reflect causality in this manner can facilitate appropriate reflex control and accurate...

WASHINGTON, June 29, 2014 /PRNewswire-USNewswire/ -- In work supported by The ALS Association, researchers have shown that increasing the clearance of misfolded protein from neurons improves their survival. The study was published today in the journal Nature Chemical Biology. http://photos.prnewswire.com/prnvar/20131211/MM32178LOGO ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects motor neurons (nerve...

bite your tongue

Alan McStravick for redOrbit.com - Your Universe Online We have all experienced it. While enjoying a delicious meal, the flavors and textures of food are delightful as we practice the mastication necessary for the beginning of the digestive process. Then, out of nowhere, our tongue fails to get out of the way of our teeth and we clamp down on the fleshy muscle, eliciting pain and, almost certainly, a few choice words. Thankfully this situation occurs with relative infrequency and, thanks...

Researchers Look For Cause Of Eye Mobility Disorder

By Steve Kehoe, The University of Iowa Normal development stalls in the nerves Imagine you cannot move your eyes up, and you cannot lift your upper eyelid. You walk through life with your head tilted upward so that your eyes look straight when they are rolled down in the eye socket. Obviously, such a condition should be corrected to allow people a normal position of their head. In order to correct this condition, one would need to understand why this happens. In a paper published in...

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by...

By studying nerve cells that originated in patients with a severe neurological disease, a University of Wisconsin-Madison researcher has pinpointed an error in protein formation that could be the root of amyotrophic lateral sclerosis. Also called Lou Gehrig's disease, ALS causes paralysis and death. According to the ALS Association, as many as 30,000 Americans are living with ALS. After a genetic mutation was discovered in a small group of ALS patients, scientists transferred that gene...

New Keck School of Medicine of USC research finds vascular damage in mice with ALS contributes to early development of the neurodegenerative disease, while repairing damage delays disease progression Keck School of Medicine of USC neuroscientists have unlocked a piece of the puzzle in the fight against Lou Gehrig's disease, a debilitating neurological disorder that robs people of their motor skills. Their findings appear in the March 3, 2014, online edition of the Proceedings of the...

Study in human cells may improve ability to identify useful drug targets In most cases of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, a toxin released by cells that normally nurture neurons in the brain and spinal cord can trigger loss of the nerve cells affected in the disease, Columbia researchers reported today in the online edition of the journal Neuron. The toxin is produced by star-shaped cells called astrocytes and kills nearby motor neurons. In ALS, the death...

Zebrafish study connects data between fish and mammalian locomotion We might have more in common with a lamprey than we think, according to a new Northwestern University study on locomotion. At its core, the study of transparent zebrafish addresses a fundamental evolution issue: How did we get here? Neuroscientists Martha W. Bagnall and David L. McLean have found that the spinal cord circuits that produce body bending in swimming fish are more complicated than previously thought....

Researchers at the University of Toronto discover how the body's muscles accidentally fall asleep while awake Normally muscles contract in order to support the body, but in a rare condition known as cataplexy the body's muscles "fall asleep" and become involuntarily paralyzed. Cataplexy is incapacitating because it leaves the affected individual awake, but either fully or partially paralyzed. It is one of the bizarre symptoms of the sleep disorder called narcolepsy. "Cataplexy is...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
