"ReMoto is a web-based neuronal simulation system, intended for studying spinal cord neuronal networks responsible for muscle control. These networks are affected by descending drive, afferent drive, and electrical nerve stimulation. The simulator may be used to investigate phenomena at several levels of organization, e.g., at the neuronal membrane level or at the whole muscle behavior level (e.g., muscle force generation). ..." <p/> alternate website
