Challenging the Axon’s Classic Shape Forget the traditional tubular shape—researchers are investigating a pearl-on-a-string formation for axons, unlocking new insights into neural signaling in health ...

Multiple sclerosis is an inflammatory disease of the central nervous system that destroys myelin, oligodendrocytes, and axons. Since most of the lesions of multiple sclerosis are not remyelinated, ...

Unmyelinated autonomic neurons express low levels of neuregulin 1 type III on the axon surface, whereas heavily myelinated axons express high levels.

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

Myelinated neurons transmit electrical signals more quickly than the unmyelinated nerves in the body. Myelinated axons are present in sensory neurons and motor neurons, but not all sensory and ...

In the grey matter, these axons are mainly unmyelinated, meaning they are not covered by a whitish-colored, fatty protein called myelin. The grey matter serves to process information in the brain.

Callosal axons release glutamate by vesicular fusion, which induces quantal AMPA receptor–mediated currents in NG2+ glial progenitors at anatomically distinct axo–glial synaptic junctions.

Gray matter is made up of neuronal cell bodies, while white matter primarily consists of myelinated axons. In the brain, white matter is found closer to the center of the brain, whereas the outer ...

Myelinated axons increases a neuron's transmission speed by as much as 100 times that of an unmyelinated axon. Myelin is not present in jawless vertebrates, which diverged from the jawed ...

Scientists have shown in both anxious rats and military veterans with PTSD that acute stress is associated with increased myelination of axons in areas of the brain associated with memory and ...

Myelinated axons increases a neuron's transmission speed by as much as 100 times that of an unmyelinated axon. Myelin is not present in jawless vertebrates, which diverged from the jawed ...
