It has been demonstrated that all functional types of the pedicel receptors (i.e. receptors maintaining the flight in the cockroach) exhibit evident directional sensitivity. The limits of maximum sensitivity to mechanical shift of the flagellum respectively pedicel in the main bulk of the sensillae lies within 90-135 degrees. The increase in the amplitude of the shift of the flagellum increases these limits. Since in all types of the sensillae receptor cells are distributed in the pedicel rather evenly and each receptor has its own band of maximum sensitivity (which differs from that of the adjacent receptors), the shift of the flagellum to any direction results in sending to the central nervous system of a relatively constant volley of nervous impulses, which presumably maintains the activity of the neurones in wing apparatus during the flight of the cockroach.
已经证明，梗节感受器的所有功能类型（即维持蟑螂飞行的感受器）都表现出明显的方向敏感性。在大多数感觉器中，鞭毛或梗节对机械位移的最大敏感极限分别在90 - 135度范围内。鞭毛位移幅度的增加会扩大这些极限。由于在所有类型的感觉器中，感受器细胞在梗节中分布相当均匀，并且每个感受器都有自己的最大敏感带（与相邻感受器的不同），鞭毛向任何方向的位移都会向中枢神经系统发送相对恒定的神经冲动群，这大概在蟑螂飞行过程中维持了翅器官中神经元的活动。
