    Abstract: An example system includes stimulation generation circuitry configured to deliver electrical stimulation to a patient; sensing circuitry configured to sense one or more biomarker signals; and processing circuitry configured to: cause delivery of electrical stimulation with the patient in a first patient state; receive a first instance of a biomarker signal in presence of the electrical stimulation with the patient in the first patient state; cause delivery of electrical stimulation with the patient in a second patient state; receive a second instance of the biomarker signal in presence of the electrical stimulation with the patient in the second patient state; determine whether a difference between the first instance of the biomarker signal and the second instance of the biomarker signal satisfies a threshold; select a therapy mode based on whether the difference satisfies the threshold; and cause delivery of electrical stimulation in accordance with the selected therapy mode.

    Abstract: Devices, systems, and techniques for monopolar recording of sensed electrical signals are disclosed. An example device includes sensing circuitry configured to sense electrical signals from a first plurality of electrode combinations, each of the first plurality of electrode combinations comprising a same reference electrode of the plurality of electrodes and at least one different sense electrode of the plurality of electrodes, the plurality of electrodes being associated with one or more leads. The example device includes processing circuitry configured to record the sensed electrical signals from the first plurality of electrode combinations. The processing circuitry is also configured to provide representations of the recorded sensed electrical signals.
