摘要 目的结合听觉生理刺激产生的机制,把经典的神经元漏积分放电模型运用于人工耳蜗信息处理编码,以期获得更好的听觉效果。方法用数字信号处理器(DSP)进行算法仿真,并把结果输入到Matlab中进行分析对比。结果在与CIS编码算法对比中,膜电位积分放电(MPIF)编码算法发放脉冲更自然,而且是伪随机的,更符合生理的结构特点。结论 MPIF方案能够有效的解决听觉信息发放序列的动态结构在听觉中枢的作用问题,使得刺激脉冲和时间编码有机的结合起来,有效的保证刺激脉冲时间的相干性和相关性。 Objective To apply the classic leakage integrate-and-fire models,based on the mechanism of the generation of physiological auditory stimulation,in the information processing coding of cochlear implants to improve the auditory result.Methods The results of algorithm simulation in digital signal processor（DSP） were imported into Matlab for a comparative analysis.Results Compared with CIS coding,the algorithm of membrane potential integrate-and-fire（MPIF） allowed more natural pulse discharge in a pseudo-random manner to better fit the physiological structures.Conclusion The MPIF algorithm can effectively solve the problem of the dynamic structure of the delivered auditory information sequence issued in the auditory center and allowed integration of the stimulating pulses and time coding to ensure the coherence and relevance of the stimulating pulse time.
