Abstract
A physiological signal of a patient is sensed with sense electrodes symmetrically arranged relative to a stimulation electrode. In some examples, a member includes a plurality of relatively small electrodes that are configured to function as both sense and stimulation electrodes. One or more of the electrodes may be selected as stimulation electrodes and two or more different electrodes of the member may be selected as sense electrodes that are symmetrically arranged relative to the one or more selected stimulation electrodes. In some examples, a member includes a plurality of levels of segmented sense electrodes and a plurality of levels of stimulation electrodes. The levels of sense electrodes are arranged such that each level of stimulation electrodes is adjacent at least two levels of sense electrodes symmetrically arranged relative to the level of stimulation electrodes.
