喂食期间 Lymnaea 颊肌的肌电图记录显示，喂食周期有 4 个组成阶段。摄食周期的电影摄影已证实，这些周期对应于延长、缩回的两个阶段和不活动阶段。肌肉活动的 4 个阶段也可以与之前描述的神经活动周期相关（Benjamin & Rose，1979）。因此，6型、4型和8型细胞是参与伸展和两个回缩阶段的运动神经元，而5型细胞在非活动期放电。生理学和解剖学方法的结合得出这样的结论：Benjamin & Rose (1979) 描述的单输入细胞和双输入细胞分别与口腔和食道活动的控制有关。
Electromyographic recordings from the buccal muscles of Lymnaea during feeding has shown that there are 4 component phases in the feeding cycle. Cinephotography of feeding cycles has confirmed that these correspond to protraction, 2 phases of retraction, and an inactive phase. The 4 phases of muscle activity can also be related to the cycle of neural activity described previously (Benjamin & Rose, 1979). Thus types 6, 4 group, and type 8 cells are motoneurones involved in protraction and the two retraction phases, while the type 5 cell fires in the inactive period. The combination of physiological and anatomical approaches has led to the suggestion that the single and double input cells described by Benjamin & Rose (1979) are involved with the control of buccal and oesophageal activity respectively.
