To determine if an axon is myelinated, several characteristics can be assessed. Here's a checklist of key features, along ...

While mutated C9ORF72 leads to some forms of amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD), scientists still wonder what the healthy protein does. In the October 10 Nature ...

Japanese and American scientists have together designed a microdevice that efficiently promotes the formation of axon fascicles from stem cell-derived neurons. The 3-D structures are common in the ...

Axonal conduction velocity, which ensures efficient function of the brain network, is related to axon diameter. Noninvasive, in vivo axon diameter estimates can be made with diffusion magnetic ...

Dorsal root ganglion nerve cells undergoing axon elongation in vitro have been analyzed ultrastructurally. The growth cone at the axonal tip contains smooth endoplasmic reticulum, vesicles, ...

While the neural architecture responsible for the transmission of electrical impulses has been known for more than a century, the basic biology behind how a neuron acquires its one and only axon -- a ...

Women have smaller, more breakable nerve fibers in the brain compared to men that may make them more susceptible to concussions, suggests a new study. Women have smaller, more breakable nerve fibers ...

Axons are the structures through which neurons transmit information to other cells. In the body, they aggregate to form fascicles. Several technologies allow scientists to generate and study single ...
