Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon. This myelination, as it is ...

A discovery led by OHSU was made possible by years of study conducted by University of Portland undergraduates. Scientists ...

As the voltage increases along the axon, additional sodium channels open, propagating the signal. The myelin sheath made of protein and fatty substances surrounds the axons of certain nerve cells and ...

"We proposed that, during evolution, the emergence of myelin coincided with the loss of lipid droplets in axon-associated ...

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.

Moreover, because myelin is produced by non-neuronal glial cells called oligodendrocytes, which myelinate axons by extending thin processes of their cell membranes to wrap around them, the study ...

Connections between neurons are called axons—long structures akin to electrical wires—and covering them is a coating ("sheath") made of myelin, a white tissue made of lipids. Comprised of up ...

The Feltri lab research focused on adhesion between myelinating cells, axons and the extracellular matrix and the ... molecular mechanisms by which mechanical signals are transduced in myelin-forming ...

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 ...

Oligodendrocytes produce the myelin sheath insulating neuronal axons (analogous to Schwann cells in the peripheral nervous system), although some oligodendrocytes (called satellite ...

The decrease in ion flux would negate the advantage of decreased capacitance, if the myelin sheath were continuous. However, at the junction between Schwann cells, the axon membrane is exposed.
