"It seems that the total amount of the myelin in the myelin sheaths is relatively preserved," says Grutzendler. Nerves are coated in myelin, but have tiny gaps called "nodes of Ranvier" where the ...
The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer’s disease. One way axonal function may be hindered is through damage to the ...
Figure 1. Development of Ranvier nodes progressed in a similar time course along NM axons after hearing onset. (A) Axonal projection of NM neurons in the chicken brainstem. Main trunk of the axon ...

This allows both to observe polarization change and to test the assumption of exponentiated transmission loss through multiple Ranvier nodes for guided light in myelin sheath waveguides. We find that ...
In neuroscience, it is of interest to consider all possible modes of information transfer between neurons in order to fully understand processing in the brain. It has been suggested that photonic ...
Nodes of Ranvier Function The myelin sheath exists in sections called internodes. Between each internode are small spaces known as nodes of Ranvier. These nodes contain positive sodium ions, which ...
Disorganization of the nodes of Ranvier noted Microscopic analyses also revealed MS-related disorganization of the nodes of Ranvier, which are gaps in the myelin sheath along myelinated axons. In ...
