When headless and intact cockroaches were trained to keep their prothoracic legs flexed to avoid electric shock, headless animals reached an asymptote more quickly than intact animals. Three behavioral measures were examined for experimental and yoked control animals to analyze differences between headless and intact animals. When cycloheximide (CXM) was injected before leg lift training, cycloheximide-injected headless animals reached an asymptote more slowly than control headless animals. However, cycloheximide did not impair leg lift learning in intact animals.
当无头和完整的蟑螂被训练保持其前胸腿弯曲以避免电击时，无头动物比完整动物更快达到渐近线。对实验动物和配对对照动物检查了三种行为指标，以分析无头动物和完整动物之间的差异。当在腿部抬起训练前注射环己酰亚胺（CXM）时，注射环己酰亚胺的无头动物比对照无头动物达到渐近线的速度更慢。然而，环己酰亚胺不会损害完整动物的腿部抬起学习。
