receiving a second bioelectrical signal sensed by the sensing module in the brain with a second sense electrode combination that is different than the first sense electrode combination;
determining a frequency domain characteristic of each of the first and second bioelectrical signals;
selecting at least one of the first or second sense electrode combinations based on the frequency domain characteristics of the first and second bioelectrical signals;
selecting a stimulation electrode combination based on the selected at least one of the first or second sense electrode combinations; and
controlling a medical device to deliver electrical stimulation to the brain of the patient via the selected stimulation electrode combination.

Abstract
Bioelectrical signals may be sensed within a brain of a patient with a plurality of sense electrode combinations. A stimulation electrode combination for delivering stimulation to the patient to manage a patient condition may be selected based on the frequency band characteristics of the sensed signals. In some examples, a stimulation electrode combination associated with the sense electrode combination that sensed a bioelectrical brain signal having a relatively highest relative beta band power level may be selected to deliver stimulation therapy to the patient. Other frequency bands characteristics may also be used to select the stimulation electrode combination.
