Recent Examples of axon from the Web
The study, published in Nature Neuroscience in August, builds on recent research where neuroscientists got RGC axons to regrow only slightly.
The fruit fly, for example, with its rapid reproduction, helped scientists understand genetics; the squid, with its peculiarly gigantic axon fibers, allowed scientists to examine the workings of a single nerve cell.
Six weeks after the injury, analysis showed that 70% of the axons in these mice had grown through the injury site, compared to only 1 or 2% in normal mice.
Some RGC axons grew all the way back to the brain’s visual-processing areas.
In a similar way, the branching of axons and dendrites from neurons also obeys local growth principles.
As the brain develops, myelin wraps itself around nerve cells’ axons—long, thin tendrils that extend from the cell and transmit information—like insulation on an electrical wire.
Besides bruising and swelling, researchers believe that force can cause the brain to elongate, stretching nerve cells and their axons — fiber-like parts that transmit messages between cells.
Second, the electrical signals those cells generate flow through neurons in one direction: branching dendrites receive the pulse, pass it to the main cell body and then along their axons—long projections that can connect distant parts of the brain.
