motor cortex

In a significant departure from earlier models, neural engineers and neuroscientists working at Stanford University have developed a new model for the brain activity underlying arm movements. Motor neurons do not represent external-world parameters as previously thought, but rather send a few basic rhythmic patterns down the spine to drive movement. The finding has implications in prosthetics, the understanding of motor disorders and other uses yet to be discovered.
