[sup] The required number may be higher in patients with diseases causing a depletion of motor axons or motor neurons
. In patients with neuropathies, larger sample size of F waves may be required than normal subjects.
EVRY, France, November 10, 2014 -- The motor neurons
that innervate muscle fibers are essential for motor activity.
French researchers at the Institute for Stem Cell Therapy and Exploration of Monogenic Diseases (1-Stem--Inserm/AFM/UEVE) here, in collaboration with CNRS and Paris Descartes University, have developed a way to better control the differentiation of human pluripotent stem cells, and thus produce different populations of motor neurons
from these cells in only 14 days.
Location motor neurons
projecting to the cat distal forelimb.
And experts know that motor neurons
need testosterone for survival and repair, and men who are born without the ability to use testosterone in the normal way develop a form of motor neuron
In the current year, the special focus is on soliciting research on gene-environment interactions as a risk factor in ALS (a fatal disease of unknown etiology marked by the progressive degeneration of motor neurons
) in order to stimulate much-needed research in this area.
are susceptible to running short of oxygen because they are "very large neurons which have to work hard to transmit signals over very long distances;' Carmeliet says.
All neurons have a fiber-like projection called an axon, and those of motor neurons
can be extremely long--over a meter--as they have to stretch from the spinal cord to the muscles of the arms and legs.
The immediate issue causing disability is within motor neurons
, specialized nerve cells that normally convey electrical impulses to achieve muscle contraction.
If the existing motor neurons
are lost due to injury or disease, electrical stimulation of nerves is rendered useless as these too are lost.
Washington, Dec 22 (ANI): In a new study, University of South Florida neuroscientists found that nutritional supplementation with Spirulina, a nutrient-rich, blue-green algae, provided neuroprotective support for dying motor neurons
in a mouse model of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.
The virus selectively attacks motor neurons
, the nerve cells that control movement, and thus kills its victims or causes permanent, partial paralysis.
