flag Researchers discover axons have a "pearl-like" structure, not cylindrical as once believed.

flag Johns Hopkins Medicine researchers have found that axons, the arm-like structures of brain cells, are not cylindrical as previously thought, but resemble pearls on a string. flag Using advanced microscopy, they observed "pearl-like" swellings along the axons. flag This new understanding of axon structure could lead to better insights into brain cell signaling and potentially inform treatments for neurodegenerative diseases.
