1. A method of determining a neural stimulation threshold for a patient, comprising: applying a test stimulation signal to the patient; monitoring a neural function of the patient for a response to the test stimulation signal; determining a neural stimulation threshold corresponding to a lowest intensity test stimulation signal that evokes the patient response; and based at least in part on the neural stimulation threshold, calculating a set of parameters of a treatment stimulation signal directed toward affecting a neural activity within the patient, wherein the treatment stimulation signal differs from the test stimulation signal with respect to a plurality of parameters.
