Muscle movement is enabled by signals conveyed from the brain to motor neurones; however, these impulses often transit through spinal interneurons before reaching their target. How the brain and this highly diverse group of "switchboard operator" cells are connected is poorly understood.
Every time you chew, talk, yawn, or sense the zap of a toothache, cranial nerve cells are shuttling electrochemical signals to your brain. Some of these neurons detect pain, while others sense facial muscle movements or sensations in the skin.
Seoul [South Korea], August 15 (ANI): An international research team has succeeded in recovering muscle movement in a model of paralysed mice organic through artificial nerves. The team was led by Prof. Tae-Woo Lee (Department of Materials Science and Engineering, Seoul National University,
