1.在蟑螂执行涉及腿部运动的几种不同类型的行为期间，可以在蟑螂的腿部记录有节奏的运动活动。在搜索和行走过程中对其进行了详细检查。2.在行走过程中，运动活动总是由一系列的爆发组成，这些爆发被沉默期隔开。在搜索过程中，它通常是连续的，但在频率上有所调制。3.有时，从搜索腿记录的运动模式是爆发式的，而不是调制。在这些情况下，通过对爆发模式的简单分析，仍然可以可靠地将其与行走期间记录的运动模式区分开来。4.在翻正过程中记录的运动模式的分析表明，这种模式更像是步行比搜索。因此，搜索不是简单的步行，因为腿与地面接触而缺乏某些周期性的感觉输入。5.它的结论是，步行和搜索可以可靠地区分彼此的基础上，在一个单一的腿部肌肉的运动活动的记录的分析。根据运动模式区分类似行为类型的能力可能在各种实验中证明是有用的。
1. Rhythmic motor activity may be recorded in the legs of cockroaches during the execution of several different types of behaviour that involve leg movements. It was examined in detail during searching and walking. 2. During walking, motor activity always consisted of a series of bursts separated by silent periods. During searching, it was usually continual, but modulated in frequency. 3. Sometimes, the motor pattern recorded from a searching leg was burst-like rather than modulated. In these cases, it could nevertheless be reliably distinguished from the motor pattern recorded during walking by a simple analysis of the burst pattern. 4. An analysis of the motor pattern recorded during righting indicated that this pattern was more like that for walking than that for searching. Therefore, searching is not simply walking that lacks certain periodic sensory input due to leg contact with the ground. 5. It is concluded that walking and searching can be reliably distinguished from one another on the basis of an analysis of a record of motor activity in a single leg muscle only. An ability to distinguish between similar types of behaviour on the basis of the motor pattern may prove useful in a variety of experiments.
