板球的前翼在飞行和摇摆两种不同的动作时被激活。细胞内记录和染色技术被用来确定这两种行为的神经元基础以及它们是如何相互关联的。这两种运动模式都是在去传入的准备中研究的。1.双功能间胸膜运动神经元(MN 90，MN 99)在飞行和颤动中以不同的突触输入模式被激活(图2).后胸椎飞行运动神经元(MN 112，MN 119，MN 129)仅在飞行中被激活，在颤动中不接受相兴奋输入(图3和6).2.两个独立的神经元间池，其中包括具有重置属性的神经元间，似乎存在，一个在飞行中激活，另一个在颤动中激活(图4和5)。这两个池之间的相互作用是抑制的。这两种运动模式可以快速切换(图6，S小于0.5%)。4.有可能同时引起两种行为，然后它们之间没有观察到严格的耦合(图7至9)。
这些观察表明，有两个不同的神经网络控制飞行和轰鸣。
SummaryThe forewing of the cricket is activated during the performance of two different behaviours, flight and stridulation. Intracellular recording and staining techniques were employed to determine the neuronal basis for these two behaviours and how they are interrelated. Both motor patterns were studied in a deafferented preparation. Stridulation was elicited by electrical stimulation of the brain and flight by brief puffs onto the cerci.1.Bifunctional mesothoracic motoneurons (MN 90, MN 99) are activated with different patterns of synaptic input during flight and stridulation (Fig. 2).2.Metathoracic flight motoneurons (MN 112, MN 119, MN 129) are only activated during flight and do not receive phasic excitatory input during stridulation (Figs. 3 and 6).3.Two separate interneuronal pools, which include interneurons with resetter properties, appear to exist, one activated during flight, the other one activated during stridulation (Figs. 4 and 5). The interactions between these two pools are inhibitory. Both motor patterns may be switched rapidly (less than 0.5 s; Fig. 6).4.It is possible to elicit both behaviours at the same time and then no strict coupling is observed between them (Figs. 7 to 9).
These observations suggest that there are two distinct neural networks which control flight and stridulation.
