Crickets have two types of mechanisms for the reception of environmental sounds: (1)the tympanal organs in the two forelegs and (2) the freely articulated setal receptors on the abdominal ceri. The cereal setal receptors have hitherto received much less experimental attention as decoders of biologically significant sounds than have the tympano-receptors. In the present study the cereal auditory system of Acheta domesticus was examined electrophysiologically to determine its auditory frequency sensitivity, the tuning characteristics of individual units, and the synchronization between nerve impulses and stimulus frequency. Both pre- and postsynaptic units were examined in the fifth abdominal ganglion; several of the observed response patterns were compared with those of homologous cereal sensory neurons in Periplaneta americana. The results show that (1) A. domesticus possesses an elaborate array of cereal receptors which are highly sensitive to sounds, (2) the cereal setal receptors are more sensitive and numerous in the cricket than in the cockroach, and (3) the cereal auditory system can decode stimulus information by narrow tuning in individual cells and by synchronous discharge patterns; firing frequencies range up to 300 Hz in presynaptic sensory units and 60 Hz in the postsynaptic giants. The response patterns were related to the structure of the receptor and the behavioural adaptations of the insect.
（1）前腿的鼓膜器官和（2）腹部的节状自由关节感受器。到目前为止，与鼓膜感受器相比，节状感受器作为生物意义声音的解码器，受到的实验关注要少得多。在本研究中，对 Acheta domesticus 的节状听觉系统进行了电生理检查，以确定其听觉频率敏感性、单个单位的调谐特性以及神经冲动与刺激频率之间的同步性。在第五个腹神经节中检查了突触前和突触后单位；将观察到的一些反应模式与 Periplaneta americana 中同源的节状感觉神经元进行了比较。结果表明：（1）A. domesticus 拥有一套精细的节状感受器，对声音高度敏感；（2）蟋蟀的节状感受器比蟑螂更敏感且数量更多；（3）节状听觉系统可以通过单个细胞的窄调谐和解码刺激信息通过同步放电模式；在突触前感觉单元中，发射频率高达 300 Hz，在后突触巨细胞中为 60 Hz。反应模式与感受器的结构和昆虫的行为适应有关。
