How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled by our ...

Researchers have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, they found unexpected potassium channels that give the ...

The evolutionary prerequisites of myelin -- the fatty substance that insulates axons and enables rapid communication between cells of the nervous system in jawed vertebrates. The evolutionary ...

Axons are the brain’s information highways, transporting cellular cargo, chemical signals, and electrical impulses to other cells. These “roads” are typically depicted as smooth and cylindrical, with ...
