The myelin sheath made of protein and fatty substances surrounds the axons of certain nerve cells and acts as an insulator, allowing actional potentials to move more quickly down the axon.

Forget the traditional tubular shape—researchers are investigating a pearl-on-a-string formation for axons, unlocking new ...

The axon initial segment (AIS) is where nerve signals begin, and its adaptability is key to brain function. Scientists have found that the AIS changes in response to activity levels, helping neurons ...

It helps transmit nerve signals, or impulses, down a long axon. All neurons have a cell body. The cell body contains important structures, such as the genetic information, energy producing ...

the oligodendrocyte sends cell processes to myelinate multiple segments on many axons (Figure 2). Although there are several molecular or morphological differences between nerve fibers in the PNS ...

Animal models as well as human cells have shown that cnicin significantly accelerates axon (nerve fibers) growth. The study ...

Axon regeneration in the central nervous ... roles in the survival and regeneration of retinal ganglion cells (RGCs) following optic nerve injuries. For instance, studies have shown that ...

the researchers found that the energy generated by oligodendrocytes from lipids could also support the electrical spiking ...

A bundle of neurones is called a nerve. There are three main types of neurone: sensory, motor and relay. They have some features in common: A long fibre (axon) which is insulated by a fatty ...
