In 2003, a German neuropathologist proposed that Parkinson's disease, which attacks the brain, actually might originate from the gut of the patients. Researchers from Aarhus have now delivered decisive supportive evidence ...

Neuroscience

First step to induce self-repair in the central nervous system

Damaged peripheral nerves can regenerate after an injury, for example, following a forearm fracture. Axons, the long projections of neurons that transmit stimuli or signals to other cells, are affected in the case of injury ...

Neuroscience

Regrowing damaged nerves hinges on shutting down key genes

Neurons in the brain and spinal cord don't grow back after injury, unlike those in the rest of the body. Cut your finger, and you'll probably be back to using it in days or weeks; slice through your spinal cord, and you likely ...
