大鼠的幽门括约肌周围放置了一个充气的袖口，两个非营养性的解决方案之间的选择。一种溶液的摄入与营养性胃内注射配对，另一种溶液的摄入与生理盐水注射配对。大鼠对营养配对口味的偏好表明，胃本身就能迅速检测到营养物质的到来。
Rats with inflated cuffs placed around the pyloric sphincter were given a choice between two nonnutritive solutions. Ingestion of one solution was paired with nutritive intragastric injections, and ingestion of the other was paired with saline injections. The preference of rats for the nutrient-paired flavors indicates that the stomach alone can rapidly detect the arrival of nutritive substances.
