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.

Abstract: The disclosure is directed to techniques for delivering electrical stimulation for patient notification. An implantable medical device (IMD) may deliver patient notification stimulation via one or more device site electrodes, e.g., electrodes located proximate to an implant site for the IMD, configured as cathodes. Anodes for delivery the patient notification stimulation may be located in an electrode array that is provided by one or more leads and located distally from the implant site, e.g., an electrode array located at one or more target sites for delivery of stimulation therapy. In some embodiments, the IMD may inhibit the patient notification stimulation for a period in response to input from the patient, and then resume the stimulation at the end of the period. In this manner, the notification stimulation may be “snoozed” like an alarm clock. When the stimulation resumes, it may be different, e.g., more urgent, then prior to inhibition.
