1. A neural stimulation system for improving neural communication between a cognitive area and a target area of a vertebrate being, said neural stimulation system being adapted to stimulate cortical and target areas coupled by neuronal connections defining a neural pathway of the being, said system comprising: a) a first stimulation signal source, said first signal source configured to deliver a first pulsed DC stimulation signal having a first set of pulses to stimulate said cognitive area on said neural pathway, said first signal source being further configured to induce a first pulsed handshake signal on said neural pathway associated with said cognitive area; b) a second stimulation signal source, said second signal source configured to deliver a second pulsed DC stimulation signal having a second set of pulses to stimulate said target area on said neural pathway, said second signal source also being configured to induce a second pulsed handshake signal on said neural pathway associated with said target area; c) a charging signal source, said charging signal source configured to supply a constant DC charging signal to said neural pathway, the neural pathway including a spinal neural communication site of the being; and d) a synchronizing component, said synchronizing component having a computer part and configured: to initiate application of said charging signal to charge-enhance performance of the neural pathway including of the spinal neural communication trigger site, and to synchronize contemporaneous convergence of the first and second pulsed handshake signals at the spinal neural communication trigger site.
