The Myelin Sheath: Shape, Size ... leaving axons and even the entire neuron vulnerable to degeneration. Thus, patients with demyelinating diseases suffer from various neurological symptoms.

A marathon taxes more than just muscles—it pushes the brain to its metabolic limits. New research shows that during extreme ...

The research is published in the journal Science. Most nerve fibers in vertebrates are encased in sheaths made largely of myelin, a protein that protects the fibers and greatly enhances the ...

Multiple sclerosis, a neuroinflammatory disease that affects nearly 3 million people worldwide, causes a loss of myelin, the fatty sheath that ... this process causes neuron damage.

Neuron Function Synapses Neural synapses are junctions between ... As the voltage increases along the axon, additional sodium channels open, propagating the signal. The myelin sheath made of protein ...

Myelin is a fatty substance produced by oligodendrocytes (cells of the central nervous system) that forms a sheath, like a kind of "insulator." It "protects" the extensions of neurons (axons ...

The APOE4 variant causes cholesterol buildup in the cells that make protective fatty sheaths for neurons ... while genes associated with myelin production were downregulated. “What we saw from the ...

My laboratory seeks to understand the molecular basis of myelination and myelin diseases. Myelin is a multi-lamellar sheath that invests large axons and permits rapid conduction of nerve signals.

A long fibre (axon) which is insulated by a fatty (myelin) sheath. They are long so they can carry messages up and down the body. Tiny branches (dendrons) which branch further as dendrites at each ...
