Touch signals from the skin are carried to the brain by intermingled projections of two pathways in the spinal cord. These pathways convey distinct features of tactile stimuli, and converge ...

Your nerves transmit messages within the brain, as well as among the brain, spinal cord, and the body. In order to do this, they use a combination of electrical and chemical signaling. Motor neurons ...

New research suggests spinal cord and brainstem are essential for processing touch signals as they travel to the brain The sense of touch is essential to almost everything we do, from routine tasks at ...

A motor evoked potential (MEP) test can determine whether there is any damage along the nerves in the brain and spinal cord. It is a painless procedure but may cause some skin discomfort. An MEP test ...

After a spinal cord injury, nearby cells quickly rush to action, forming protective scar tissue around the damaged area to stabilize and protect it. But over time, too much scarring can prevent nerves ...

The sense of touch is essential to almost everything we do, from routine tasks at home to navigating unfamiliar terrains that may conceal dangers. Scientists have long been interested in understanding ...

A research team from the University of Cologne has shown how zebrafish can rebuild their nerve pathways and restore their locomotor function after a spinal cord injury. Specialized connective tissue ...

Stroke and spinal cord injuries can severely impair motor functions, and understanding how to promote recovery is a critical challenge. While damaged neurons in the brain and spinal cord have limited ...

Roccati, age 31, is one of three men who received experimental spinal cord stimulators as part of a clinical trial. All three had completely paralyzed lower bodies. The results have been a stunning ...
