Abstract:
1. A system comprising: a plurality of electrodes; a sensing module that senses a plurality of bioelectrical brain signals, each of the plurality of bioelectrical brain signals being sensed via at least one respective electrode of the plurality of electrodes; and a processor that determines a frequency domain characteristic for each of the plurality of bioelectrical signals; determines a plurality of relative values of the frequency domain characteristic, wherein each of the plurality of relative values is based on at least two of the frequency domain characteristics; determines whether a first relative value of the plurality of relative values is greater than or less than at least one other relative value of the plurality of relative values; in response to determining that the first relative value is greater than or less than the at least one other relative value, determines whether a second relative value of the plurality of relative values is greater than or less than another relative value of the plurality of relative values; determines whether a target tissue site is positioned between two electrodes of the plurality of electrodes based on determining whether the first relative value is greater than or less than at least one other relative value and based on determining whether the second relative value is greater than or less than another relative value; and selects at least one electrode of the plurality of electrodes for delivering stimulation to the patient based on determining whether the target tissue site is positioned between the two electrodes.
