摘　　要：The structure and function of the cercus-to-giant interneuron system,relevant to the receptionof low-frequency sound,within the terminal abdominal ganglion of the locust Locusta migratoria were revealedby using intracellular electrophysiological recording and dye labeling technique.This system consists of 4 bilater-al pairs of the giant interneurons(GIs 1—4).Each GI has distinct dendritic branching fields,position of thesoma,and location and orientation of its major axon.The characteristics of the system in responseto low-frequency sound,such as discharge patterns,the relationships between response threshold-frequency,in-tensity curves,and encoding of stimulus frequency,were also studied.The role of the system in low-frequencysound communication was discussed.The structure and function of the cercus-to-giant interneuron system,relevant to the reception of low-frequency sound,within the terminal abdominal ganglion of the locust Locusta migratoria were revealed by using intracellular electrophysiological recording and dye labeling technique.This system consists of 4 bilater- al pairs of the giant interneurons(GIs 1—4).Each GI has distinct dendritic branching fields,position of the soma,and location and orientation of its major axon.The characteristics of the system in response to low-frequency sound,such as discharge patterns,the relationships between response threshold-frequency,in- tensity curves,and encoding of stimulus frequency,were also studied.The role of the system in low-frequency sound communication was discussed.
