Scientists Debunk 100-Year-Old Theory of Brain Cell Structure

Credit: Birth Into Being / CC BY-NC-SA 2.0 For more than a century, scientists assumed the thin extensions of brain cells that carry electrical signals, known as axons, were smooth, tube-shaped structures. A new study debunks that long-standing view of brain cell structure, showing that axons instead form a repeated pearl-like pattern under near-natural conditions. This shape directly controls how fast signals travel through the brain. The findings, published in Nature Neuroscience, come from researchers at Johns Hopkins University School of Medicine. Lead...
