New research describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses. New research from the University of North Carolina at Chapel Hill School ...

The discovery in electron micrographs of a synaptic bouton arising directly from a node of Ranvier in the motor horn of the monkey spinal cord, and of a node covered by extensions of two outer ...

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 ...

An early concept of glial function envisaged them as passive and unexcitable structural elements, much like the connective tissues of organs in the periphery. It is now known that glia have a ...

The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed of ...
