rat after stroke

University of Zurich Only if the timing, dosage and kind of rehabilitation are right can motor functions make an almost full recovery after a large stroke. Rats that were paralyzed down one side by a stroke almost managed to regain their motor functions fully if they were given the ideal combination of rehabilitative training and substances that boosted the growth of nerve fibers. Anatomical studies confirmed the importance of the right rehabilitation schedule: Depending on the therapeutic...

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...

Scientists at the Salk Institute have discovered the developmental source for a key type of neuron that allows animals to walk, a finding that could help pave the way for new therapies for spinal cord injuries or other motor impairments related to disease. The spinal cord contains a network of neurons that are able to operate largely in an autonomous manner, thus allowing animals to carry out simple rhythmic walking movements with minimal attention—giving us the ability, for example, to...

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...

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...
