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 ...
How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled by our ...
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, ...
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 ...
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 ...
Penn State scientists have developed artificial axons that could be used to replace the broken axon pathways and neurons in the brains of individuals who have suffered head trauma. Axons, which ...
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 ...
