摘　　要：蝙蝠具有高度发达的回声定位系统,能够准确地处理和整合不断变化环境中的声学参数,以保持最佳的生理和行为状态。这种行为的神经生理机制已经得到了广泛的研究。本文主要探究了CF-FM蝙蝠听觉中枢处理种属特异性声信号、共变参数、多普勒频移补偿信号及多谐波声信号的神经机制,可有助于了解回声定位蝙蝠处理行为相关声信号的神经策略。同时本文也提出将来可以CF-FM蝙蝠作为模式动物进行更深入的胞内研究。Due to a highly developed echo location system,bats can accurately process and integrate acoustic parameters of fluctuating environments to maintain optimum physiological and behavioral status.The neurophysiological mechanisms of this behavior have been extensively studied and it’s time to review the progress of this research.This review is mainly about the neural mechanism underlying in species-specific signal recognition,co-varying parameters processing,Doppler-shift compensation and multi-harmonic signals processing which is related to echolocation.It will not only help us understand the strategy of how the bat auditory system processes behavior-related acoustic signals,but also to raise some issues that remained unresolved,which need further intracellular studies in CF-FM bats as a model in the future.
