Beyond the Smooth Cable: New Research Reveals Dynamic ‘Pearled’ Architecture in Brain Axons
For over a century, textbooks have taught students that axons—the long, slender extensions of neurons responsible for transmitting electrical signals—are essentially smooth, uniform tubes. This classic illustration, which depicts these vital cellular cables as narrow, consistent conduits, has served as a foundational concept in neuroscience. However, a groundbreaking study from Johns Hopkins Medicine, published in…
