Methods and equipment used to regenerate sensory, motorial, or visceral signals of injured, broken or diseased nerves of mammalia, such as humans, are provided. In some embodiments, a lineup of downward and upward channels to bridge injured neural channels is disclosed. The downward or upward channels can be connected to electrodes which are in contact with upper or lower nerve stumps. The channels can be used to detect, amplify, and recognize the motorial or sensory signals, to generate related Functional Electrical Stimulation (FES) signals, and to supply the FES signals to the electrodes on the lower or upper nerve stumps. Neural signals can thus be regenerated and the injured motorial or sensory channels can be bridged.
