| Abstract: | Postnatal development of auditory brainstem responses(ABR)and auditory middle latency responses(M LR)had been studied continously for three months in the same group of rat pups.After birth,ABR and MLR were evoked at 14 and 17 days respectively.The peak latencies of ABR's waves shortened rapidly at first postnatal month,which occurred more quickly in the wave origi- nated from the lower structures of the auditoy brainstem pathway.The peak latencies of MLR's waves obviously shortened also,at first postnatal month,which occurred more quickly in the wave originated from the lower structures of auditory pathway.These results suggested that fisrt month af- ter birth was the most important period for development of function of auditory nervous system in rats,which proceeded in a centripetal sequence from the most peripheral to the rostral structures. |
