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.
对椎实螺进食期间颊肌的肌电图记录显示，进食周期有4个组成阶段。进食周期的电影摄影证实，这些阶段分别对应于伸展、两个收缩阶段和一个静止阶段。肌肉活动的这4个阶段也与之前描述的神经活动周期相关（本杰明和罗斯，1979年）。因此，6型、4组和8型细胞是参与伸展和两个收缩阶段的运动神经元，而5型细胞在静止期放电。生理学和解剖学方法的结合表明，本杰明和罗斯（1979年）描述的单输入和双输入细胞分别参与颊部和食管活动的控制。
