Briefly, a gadolinium‐based contrast agent was mixed with the animal’s meal in order for chyme to appear “bright” in MRI scans, thereby delineating the gastric and intestinal volume. A multi‐slice MRI sequence was used to scan antral contractions with high spatial and temporal resolution. The configuration of VNS was varied in terms of pulse parameters (amplitude, width, and frequency)."}}
