Electrode placement on the isolated, left cervical vagus of a swine for the LFAC experiments. The CE, a bipolar cuff, was used for vagal stimulation. The LFAC conditioning waveform was presented at the RE. A tripolar recording electrode for ENG recordings was placed most rostral on the vagus nerve and secured with suture. A ligature was placed caudal to all three electrodes to eliminate cardiac effects due to stimulation of the left vagus nerve
