Highly developed odor learning was shown in the terrestrial slug Limax maximus. In addition, several key cellular elements of the neural network that controls ingestive feeding have been identified. The results of 3 experiments demonstrate an interaction between odor input and ingestive feeding in that olfactory stimulation with behaviorally attractive odors summed with tactile stimulation from plain agar to produce ingestion of plain agar. Agar ingestion did not occur in the absence of attractive odor stimulation. The adequacy of odor stimulation to trigger agar ingestion was altered by associative learning. Innately attractive odors rendered repellent by associative learning no longer triggered agar ingestion, whereas innately repellent odors rendered attractive by conditioning triggered agar ingestion. The newly discovered feeding command cells in the Limax cerebral ganglion are a logical cellular locus for this interaction.
在陆生蛞蝓大蛞蝓（Limax maximus）中表现出了高度发达的气味学习能力。此外，已经确定了控制摄食性进食的神经网络的几个关键细胞元件。3个实验的结果表明，气味输入与摄食性进食之间存在相互作用，即具有行为吸引力的气味的嗅觉刺激与来自普通琼脂的触觉刺激相加，会导致普通琼脂的摄入。在没有有吸引力的气味刺激的情况下，琼脂摄入不会发生。联想学习改变了触发琼脂摄入的气味刺激的充分性。通过联想学习变得具有排斥性的先天具有吸引力的气味不再触发琼脂摄入，而通过条件作用变得具有吸引力的先天具有排斥性的气味则触发琼脂摄入。在大蛞蝓脑神经节中新发现的进食指令细胞是这种相互作用的一个合理的细胞位点。
