TORONTO -- A thinner-than-normal layer of retinal nerve fibers
in the eye is now linked with cognitive decline--another suggestion that extracranial physical findings could be leveraged into dementia screening tools.
HOKKAIDO, Japan, April 15, 2016 -- Researchers here have for the first time used stem cells to promote regeneration after injury to a specialized band of nerve fibers
that are important for motor function.
Several investigators have reported that a larger ONH had more optic nerve fibers
as determined histologically in human eyes.
In an SCS system, an IPG generates electrical energy, which is delivered via leads to nerve fibers
along the spine to interrupt pain signals as they travel to the brain, reducing the sensation of pain.
These proteins in the tissue around the nerve fibers
inhibit nerve-fiber growth.
The cornea is the most densely innervated tissue in the body, so corneal nerve assessment is extremely sensitive for detecting small sensory nerve fiber
damage as compared to other tests including measurement of intra-epidermal nerve fibers
in the skin, notes lead investigator Joseph L.
Wide-spread myelinated nerve fibers
of the optic disc: do they influence the development of myopia.
The intrapapillary retinal nerve fibers
form the neuroretinal rim.
Spinal cord injuries sever nerve fibers
that conduct signals between the brain and the rest of the body, causing various degrees of paralysis depending on the site and extend of the injury.
Research scientists used a fluorescence microscope to label different nerve fibers
designated by specific markers.
The new study by Experts in magnetic resonance imaging from The University of Nottingham's Sir Peter Mansfield Magnetic Resonance Centre reveals why images of the brain produced using the latest MRI techniques are so sensitive to the direction in which nerve fibers
In MS, the immune system damages and destroys myelin, the material that surrounds and protects nerve fibers
in the brain and spinal cord.
