1. A method of effectuating a neural-function of a patient, comprising: selecting a stimulation site by (a) generating an intended neural activity by triggering a neural signal from an impaired body part affected by neural dysfunction of the patient's brain, wherein triggering a neural signal includes moving, stimulating or moving and stimulating the impaired body part, (b) detecting a cortical region of the brain in which a response to neural activity occurs in reaction to the neural signal, the detected cortical region being at a cortical location of the brain different than a normal cortical location of the brain where neural activity typically occurs to carry out a function of the impaired body part, and (c) selecting the stimulation site to be within the detected cortical region; positioning at least a first electrode at the stimulation site; and applying an electrical potential to pass a current through the first electrode.
