Head Impacts and Brain Decay. Brain injury in sports may trigger an autoimmune reaction in which the body attacks the brain. Listen to CBC

Why can't I control my individual toes?

11 Questions for Christopher Reeve. Christopher Reeve’s son, Matthew, has created a poignant and sincere portrait about the man known to the world as Superman, as he relentlessly fought to overcome paralysis after a horse-back riding accident in 1995. Christopher Reeve talks about his wheelchair on Sesame Street..

Neuromotor prostheses (NMPs) aim to replace or restore lost motor functions in paralysed humans by routeing movement-related signals from the brain, around damaged parts of the nervous system, to external effectors. Watch Matthew Nagle, a patient with spinal cord injury, draw a circle using a chip implanted over his motor cortex.

Check out these videos (allow pop ups on your browswer). A great site for the video's of several aspects of the neurological exam from the University of Utah. Check out

Beginning in the 1940s, Canadian brain surgeon Wilder Penfield mapped the brain's motor cortex -- the area that controls the movement of your body's muscles. He did this by applying mild electric currents to the exposed brains of patients while they were in surgery. Now you can relive his exploration of the brain. In the following feature we give you an electric probe and an exposed brain. All you need to do is shock and observe. Try the Probe The Brain Shockwave Animation from PBS.

Neurons Developed from Stem Cells Successfully Wired With Other Brain Regions in Animals. "These stem cell-derived neurons can grow nerve fibers between the brain's cerebral cortex and the spinal cord, so this study confirms the use of stem cells for therapeutic goals," James Weimannof Stanford Medical School.
