An example of a method embodiment may place a set of stimulation electrodes on tissue containing the baroreceptor region, and may test bipolar configurations of the electrodes. Each of the bipolar configurations of the electrodes includes at least one of the electrodes configured to function as an anode and at least one other of the electrodes configured to function as a cathode. Testing the bipolar configurations may include stimulating the tissue using each of the bipolar configurations. For each of the tested bipolar configurations at least one physiological parameter may be monitored for a baroreflex response to stimulation of the tissue, and the baroreflex response may be recorded for each of the tested bipolar configurations.
