ABVN Phase 2-Studying the Effect of Stimulation on the Auricular Branch of the Vagal Nerve -B

"Cervical neck electrodes used in this part of the study will include the multi electrode array (MEA). The MEA can be placed on either side of the neck over the area of the vagus nerve to record any electrical activity that might occur during the baseline period.~Two ECG electrodes are placed either one on each arm or on the chest for measurement of the electrocardiogram (ECG).~Three ECG electrodes are placed on the abdomen in a line parallel to the longitudinal axis of the stomach to record the electrogastrogram (EGG).~A onetime baseline recording will be made for 20 minutes after which the subject will be discharged from the study."
