Claim:
1. A method, comprising: controlling the delivery of electrical stimulation from a medical device to a brain of a patient at a plurality of different levels of a stimulation parameter; sensing, using one or more electrodes, bioelectrical brain activity of the brain of the patient, wherein sensing the bioelectrical brain activity comprises sensing a bioelectrical response of the brain to the delivery of the electrical stimulation at each of the plurality of different levels of the stimulation parameter; identifying, based on the sensed bioelectrical brain activity, a window of the stimulation parameter, the window having a first threshold as a lower boundary for the stimulation parameter level, a second threshold as an upper boundary for the stimulation parameter level, and a range of stimulation parameter levels between the lower boundary and the upper boundary, wherein the first threshold is a suppression threshold and the second threshold is an after-discharge threshold; determining, based on the identified window, an aspect of therapy to be delivered to the brain of the patient; and controlling the delivery of the therapy to the brain of the patient according to the determined aspect, wherein the sensing, the controlling, the identifying, and the determining are each performed, at least in part, by control circuitry.
