Aplysia can be taught to stop responding to inedible food, by pairing lip stimuli with stimuli arising from food stuck in the buccal cavity. When the esophageal nerves innervating the gut are cut. Aplysia cease responding to inedible food in a mean of 2.09 times longer than when these nerves are intact. Patterning of feeding movements is also changed. Cessation of responses in lesioned animals may be due to adaptation caused by lip stimulation. The data suggest that the esophageal nerves carry information about whether food is edible or inedible.
通过将唇部刺激与口腔中卡住的食物产生的刺激配对，海兔可以被训练停止对不可食用食物做出反应。当支配肠道的食管神经被切断时，海兔停止对不可食用食物做出反应的平均时间比这些神经完好时延长2.09倍。进食动作的模式也会改变。受损动物反应的停止可能是由于唇部刺激引起的适应。数据表明，食管神经携带有关食物是否可食用的信息。
