1. A system for improving neural communication impairment of a vertebrate being, the system comprising: a first signal providing component configured to provide pulsed peripheral stimulation signals at a peripheral body part through a first signal transmission component for generating a first stimulation signal along a neural pathway; a second signal providing component configured to provide a pulsed motor cortex stimulation signal to a motor cortex area through a second signal transmission component for generating a second stimulation signal along the neural pathway; and a DC signal providing component configured to provide a constant-level direct current spinal stimulation signal to a neural spinal junction on the neural pathway.
