Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, ...

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 ...

A discovery that may improve treatment options for patients with neurodegenerative diseases. A discovery that may improve treatment options for patients with neurodegenerative diseases has been made ...

This protective layer allows signals to pass between cells incredibly quickly. But what happens when this layer goes missing ...

Human brains (and the brains of other vertebrates) are able to process information faster because of myelin, a fatty substance that forms a protective sheath over the axons of our nerve cells and ...

Injuries to the nerves can blind or paralyze because adult nerve cells don’t regenerate their connections. Now, a team of UConn School of Medicine researchers report in Development that at least a ...

When laboratory mice suffer brain damage, e.g., from an injection, research group leader Jan Deussing has observed that a ...

Traumatic injury to the brain, spinal cord and optic nerve in the central nervous system (CNS) are the leading cause of disability and the second leading cause of death worldwide. CNS injuries often ...

Stay up to date on the latest science with Brush Up Summaries. Nerve cells, or neurons, are the basic functional units of the nervous system. Multiple interconnected neurons form a neural circuit and ...
