Time lapse photography of slugs living in an experimental enclosure shows that these animals can return to a homesite from over 90 cm by a direct route. Slime trail following and vision are not involved in this behavior. In the presence of a low velocity wind, homing occurs upwind. Surgical disconnection of the presumptive olfactory apparatus (digitate ganglion) from the central nervous system eliminates homing. Neurophysiological recordings from the receptor surface associated with the digitate ganglion and the olfactory nerve demonstrate the olfactory function of the digitate ganglion. The olfactory acuity and capacity for directed locomotion via olfactory cues are also relevant to studies of slug feeding behavior, ecology, and learning ability.
对生活在实验围栏中的蛞蝓进行的延时摄影表明，这些动物能够通过直接路线从90多厘米外返回栖息地。这种行为不涉及沿着黏液痕迹追踪和视觉。在存在低速风的情况下，归巢行为会逆风发生。将假定的嗅觉器官（指状神经节）与中枢神经系统进行手术切断会消除归巢行为。来自与指状神经节和嗅神经相关的感受器表面的神经生理学记录证明了指状神经节的嗅觉功能。嗅觉敏锐度以及通过嗅觉线索进行定向运动的能力也与蛞蝓的进食行为、生态学和学习能力的研究相关。
