Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike structure of mammalian brain cells may be a different shape than scientists have ...

Capitalizing on the flexibility of tiny cells inside the body's smallest blood vessels may be a powerful spinal cord repair strategy, new research suggests. In mouse experiments, scientists introduced ...

The ultrathin tendrils that zip messages around the nervous system are often drawn as smooth lines. But a new study adds some flourishes to that classical picture. Like a garland of cranberries hung ...

In a study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to cell ...

Axons are the brain’s information highways, transporting cellular cargo, chemical signals, and electrical impulses to other cells. These “roads” are typically depicted as smooth and cylindrical, with ...
