In the late 1800s, Spanish neuroscientist Santiago Ramón y Cajal drew hundreds of images of neurons. His exquisite work influenced our understanding of what they look like: Cells with a bulbous center ...

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 ...

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 ...

WOODS HOLE, Mass. -- In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit ...

Biology textbooks may need a revision, say scientists, who present new evidence that an arm-like structure of mammalian brain cells may be a different shape than scientists have assumed for more than ...

A new study suggests that how neurons process energy may determine whether they resist damage or begin to break down.

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...

Explore new insights into neurodegenerative therapies as researchers observe learning mechanisms in the living brain.

Researchers have engineered a next-generation glutamate sensor, iGluSnFR4, capable of detecting the faintest incoming ...

Each year, according to the National Institutes of Health (NIH), millions of people in the U.S. are affected by spinal cord and traumatic brain injuries, along with neuro-developmental and ...
