Someone has a stroke every 40 seconds in the US, resulting in death every 4 minutes. Stroke is the leading cause of disability from a medical condition. When it happens, blood clots or bleeds kill a part of the brain – it goes dark – and can no longer control part of the body. People stop being able to walk, see, talk, or control their hand or arm the way they once did. Although treatments…

Thanks to a four-limb robotic system controlled by brain signals, a patient with a cervical spinal cord injury could walk and control both arms for the first time in a proof of concept. Developed by CEA (French Alternative Energies and Atomic Energy Commission), the system is driven via the long-term implant of a semi-invasive medical device to record brain activity.
Researchers have created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders.
Neurons of the central nervous system (CNS) shut down their ability to grow when they no longer need it; this is commonly accepted knowledge. This occurs normally after they have found their target cells and established synapses. However, recent findings show that old nerve cells have the potential to regrow and to repair damage similar to young neurons. The underlying mechanisms for this…
Inside the body, disease and injury can leave behind quite the mess — a scattering of cellular debris, like bits of broken glass, rubber and steel left behind in a car accident. Inside the central nervous system (CNS), a region that includes the brain and spinal cord, it is the job of certain cells, called microglia, to clean up that cellular debris. Microglia have counterparts called…
A world where machines can be controlled by thought alone – such is the promise of so-called brain-computer interfaces (BCI). BCIs are both hardware and software communication systems that read brain and nerve signals, convert those into electrical signals and translate human thoughts into machine commands. Developers of BCIs rely on artificial intelligence, neural network models and big data…

Her goal and her scientific approach to develop an injectable material with the ability to provide biochemical and physical guidance for regenerating nerves across the injury site, was selected…
Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. An international team of researchers led by DZNE scientists in Bonn now reports in Science that help might be on the way from an unexpected quarter: in animal studies, the cancer drug epothilone…

“My dream is that children with neurological motion disorders will travel through virtual worlds with the help of a robotic gait orthosis. For example, they might explore a farm, smelling the country air and hearing the chickens cluck; while this is happening, the robot would provide them with physiological gait training”, said Professor Paolo Bonato, Director of the Motion Analysis…

Surgery in the lower pelvic region often involves injury to or severing of nerve tissue. As in chronic diseases of the nervous system, the result can be pain, sensory disturbances or loss of function. Up to now the poor view of the nerves, partially formed of fine interwoven networks, has been one of the major problems – exacerbated by the strict division of skills between neurologists and…
