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 ...

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 ...

The hypothesis that it disrupts the function of retinal ganglion cell axons by increasing mechanical forces on the lamina cribrosa of the optic nerve head has received considerable experimental ...

This causes an influx of positive sodium ions into the cell, raising the voltage and depolarizing the membrane. As the voltage increases along the axon, additional sodium channels open, propagating ...

In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signal ...

A long fibre (axon) which is insulated by a fatty (myelin ... These receive incoming impulses from other neurones. Receptor cells detect a change in the environment (a stimulus) and start ...

Dietmar Fischer. Animal models as well as human cells have shown that cnicin significantly accelerates axon (nerve fibers) ...

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 ...
