After cutting the nervous chain at different levels, separate fragments of motor component of foodgetting behaviour of the crayfish disappeared. Separation of the supraoesophageal ganglion from the nervous chain results in the abolition of food searching phase, control and organization of aimed locomotions, fixation of the body with respect to the target objects. At the same time the activity of separate functional blocks becomes more evident being realized in automatic regime with the trigger type of its onset. Suboesophageal ganglion structures initiate the spontaneous non-coordinated locomotor activity of the postural and locomotor apparatus and provide for realization of the whole algorhythm: grasping the food, driving the claw to the rostral part of the body, transmission the food to the II-III pairs of walking legs and then to the mouth opening. Structures of the 1st isolated thoracal ganglion realize grasping and holding reflex which is going on slowly and inactively.
在不同水平切断神经链后，小龙虾获取食物行为的运动成分的各个片段消失。将食管上神经节与神经链分离会导致食物搜索阶段、定向运动的控制和组织以及身体相对于目标物体的固定被消除。与此同时，各个功能块的活动在其触发式开始的自动模式下变得更加明显。食管下神经节结构引发姿势和运动装置的自发非协调运动活动，并确保整个算法节律的实现：抓取食物、将爪子驱动到身体的吻部、将食物传递到第二至三对步足，然后传递到口部开口。第一个分离的胸神经节的结构实现缓慢且不活跃的抓握和握持反射。
