1. A computer-implemented method for generating a target stimulation region, the method comprising: for a plurality of electrode stimulations performed on at least one patient, identifying, by a computer processor, which neural elements were indicated to have been activated in a predetermined threshold number of the plurality of electrode stimulations; and outputting, by the processor, the identified neural elements as a target stimulation region for producing a clinical effect; wherein: a respective axonal model is generated for each of the at least one patient; for each of the plurality of electrode stimulations performed on the at least one patient, a respective stimulation model is generated, the respective stimulation model being of those axons of the axonal model, of the patient on which the stimulation was performed, which were activated by the respective electrode stimulation; and the identifying is based on the stimulation models.
