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...

And how do separate small elements come together to become a unique and meaningful sequence? When you learn how to play the piano, first you have to learn notes, scales and chords and only then will you be able to play a piece of music. The same principle applies to speech and to reading, where instead of scales you have to learn the alphabet and the rules of grammar. But how do separate small elements come together to become a unique and meaningful sequence? It has been shown that a...

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....

Fidgetin inhibition: Potential new therapeutic approach to promote tissue regeneration & repair of broken cell connections Suppressing the enzyme fidgetin promotes the re-growth of experimentally injured nerve cells and their connections, according to research with laboratory rats that will be presented Tuesday, Dec. 17, at the American Society for Cell Biology (ASCB) annual meeting in New Orleans. If additional studies confirm these results, fidgetin inhibition could be a potential...

Synaptosomal-associated protein-25 is an important factor for synaptic functions and cognition. Prof. Zhong Wang and team from the First Affiliated Hospital of Soochow University, China verified that synaptosomal-associated protein-25 expression in the temporal lobe, hippocampus, and cerebellum significantly lower at days 1 and 3 following subarachnoid hemorrhage using immunohistochemical staining and western blot analysis. Synaptosomal-associated protein-25 expression was significantly lower...

Kennedy Krieger Institute researchers find that damage to the cerebellum impairs ability to predict motion outcomes and discrimination between limb positions BALTIMORE, Sept. 4, 2013 /PRNewswire-USNewswire/ -- Researchers at the Kennedy Krieger Institute announced today study findings showing, for the first time, the link between the brain's cerebellum and proprioception, or the body's ability to sense movement and joint and limb position. Published in The Journal of Neuroscience, the study...

Stem Cell Spinal Injury Treatment Breakthrough

Brett Smith for redOrbit.com - Your Universe Online For years, stem-cell based therapies have been described as a potential way to treat spinal cord injuries in humans, and a new study published in the journal Stem Cell Research and Therapy describes an exciting step forward in that pursuit. According to the report, a single injection of human stem cells was able to induce neuronal regeneration and improved mobility in rats that were afflicted with a severe spinal cord injury. "This...

Brain's elusive motor neurons are dressed in fluorescence so scientists can find them and study why they die A small group of elusive neurons in the brain's cortex play a big role in ALS (amyotrophic lateral sclerosis), a swift and fatal neurodegenerative disease that paralyzes its victims. But the neurons have always been difficult to study because there are so few of them and they look so similar to other neurons in the cortex. In a new preclinical study, a Northwestern Medicine®...

Neuron Transformation In The Brain Opens A New Avenue In Neurobiology
2013-01-21 04:44:13

redOrbit Staff & Wire Reports - Your Universe Online A pair of Harvard University stem cell biologists have reportedly demonstrated a technique with which they can transform one type of already differentiated neuron into another. The discovery, reported by the Cambridge, Massachusetts-based Ivy League school in a statement released Sunday, demonstrates it is possible that the human brain “is not as immutable as we always thought, because at least during an early window of time...

Insect research yields insights for muscle control and nerve disorders in mammals, including humans Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins´ mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad...
