中枢神经系统的某些部分在控制进食行为，特别是咀嚼中的作用，已经通过使用损伤进行了研究，切断食管下神经节后的连接可以解除咀嚼的抑制，这样即使在没有机械刺激或化学刺激的情况下，也会发生连续的有节奏的下颌运动。 用植物材料刺激口器会导致咀嚼速率的增加并维持摄食。将食道下神经节与前脑分离并不能阻止咀嚼和维持摄食的诱导。 切断额叶连接（单侧或双侧）可以消除持续的摄食，但不能消除咀嚼能力。中央分离的食管下神经节能够产生协调的咀嚼行为，但不能产生摄食性食物。
The role of certain parts of the central nervous system in the control of feeding behaviour, and especially of chewing, has been investigated by the use of lesions.Cutting the connectives behind the suboesophageal ganglion disinhibits chewing, so that continuous rhythmic mandibular movements occur even in the absence of mechano- or chemostimulation of the mouthparts. Stimulation of the mouthparts with plant material leads to an increased rate of chewing and to maintained ingestion.Isolating the suboesophageal ganglion from the protocerebrum does not prevent the induction of chewing and maintained ingestion. Severing the frontal connectives (uni- or bilaterally) eliminates maintained ingestion but not the ability to chew.The centrally isolated suboesophageal ganglion is capable of producing a co-ordinated chewing behaviour, but not of ingesting food.
