Memories and learning processes are based on changes in the brain's neuronal connections, and as a result, in signal ...

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 ...

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 ...

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 ...

Unlike the brain and spinal cord, peripheral nerve cells, whose long extensions reach the skin and internal organs, are capable of regenerating after injury. This is why injuries to the central ...

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

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

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 ...

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 ...

Myelin loss disrupts the coordination of signals between brain regions, impairing the accurate processing of information, researchers found.
