切除实验表明，在几种甲壳类动物中，近端眼柄神经节在多种行为模式中起重要作用：1.切除双侧眼柄改变了龙虾、寄居蟹和某些短尾蟹通过触角的化学诱食;切除一个触角和对侧眼柄对龙虾和寄居蟹有效; 2.切除眼柄后，所有三组动物都增加了对不可食用物体的咀嚼; 3.在眼柄切除后，龙虾和寄居蟹的姿势发生改变; 4.在无眼柄动物中，龙虾的逃避反应仅在相当大的触觉输入后发生; 5.寄居蟹在眼柄完全切除后进入壳需要更长的时间，这与仅切除双眼远端元件的对照手术相反。
这表明，所有的行为改变后看到的眼柄消融可以被认为是一个结果，消除了时间衰减的刺激输入themedulla终。
SummaryAblation experiments demonstrated that in several crustacean groups, the proximal eyestalk ganglia are important in a variety of behavior patterns:1.Chemical elicitation of feeding via the antennules is altered in lobsters, hermit crabs, and some brachyuran crabs by bilateral eyestalk ablation; the ablation of one antennule and the contralateral eyestalk is effective in lobsters and hermit crabs;2.increased chewing of inedible objects occurs in all three groups following eyestalk ablation;3.postural alterations in lobsters and hermit crabs occur following eyestalk ablation;4.escape responses in lobsters occur only after considerable tactile input in eyestalk-less animals;5.shell entry by hermit crabs takes much longer following complete eyestalk ablation, in contrast to control operations in which just the distal elements of both eyes are removed.
It is suggested that all of the behavioral alterations seen following eyestalk ablation can be considered a result of the removal of temporal attenuation of stimulus input by themedulla terminalis.
