The feeding motor program(FMP) of the terrestrial slug Limax maximus was examined in vivo and in vitro. The feeding pattern of intact animals shows an initial increase in bite frequency followed by a plateau phase. Recordings obtained from semi-intact preparations of the lips, brain, and buccal mass established the correlation of activity in buccal ganglion nerve roots with the protraction-retraction bite cycle. A preparation of the lips, cerebral ganglia, and buccal ganglia was developed, such that, repetitive chemostimulation of the lips yields reproducible bouts of FMP. Sources of proprioceptive feedback from buccal muscles were demonstrated. The feasibility of computer scoring of the FMP is documented. The results demonstrate that aspects of in vivo feeding behavior are retained and identifiable in highly dissected, in vivo preparations.
对陆生蛞蝓大蛞蝓的摄食运动程序（FMP）进行了体内和体外研究。完整动物的摄食模式显示，咬食频率最初会增加，随后进入平稳阶段。从唇部、脑部和口腔团块的半完整制剂中获得的记录，确定了口腔神经节神经根活动与伸缩咬食周期之间的相关性。开发了一种唇部、脑神经节和口腔神经节的制剂，使得对唇部进行重复性化学刺激可产生可重复的FMP发作。证明了来自口腔肌肉的本体感受反馈来源。记录了对FMP进行计算机评分的可行性。结果表明，在高度解剖的体内制剂中，体内摄食行为的各个方面得以保留且可识别。
