【摘要】:聽神經(jīng)復(fù)合動(dòng)作電位(CAPs)的閾值曲線和調(diào)諧曲線分別反映了聽神經(jīng)系統(tǒng)對刺激聲的強(qiáng)度靈敏度和頻率靈敏度。為了全面、客觀、方便地提取聽神經(jīng)系統(tǒng)的信息,該文基于多媒體外置聲卡、使用C#語言編寫對聲卡的控制程序設(shè)計(jì)了CAPs檢測系統(tǒng),實(shí)現(xiàn)了對聲音刺激下CAPs電信號的采集,并獲取了用于表征聽神經(jīng)系統(tǒng)功能狀況的CAP閾值曲線和調(diào)諧曲線。該系統(tǒng)為聽神經(jīng)復(fù)合動(dòng)作電位的檢測和后續(xù)研究提供了綜合、客觀的分析研究平臺,具有較高的使用價(jià)值。
[Abstract]:The threshold curve and tuning curve of auditory nerve compound action potential (CAPs) reflect the intensity sensitivity and frequency sensitivity of auditory nervous system to stimulatory sound, respectively. In order to extract the information of the auditory nervous system comprehensively, objectively and conveniently, this paper, based on the multimedia external sound card, designs the CAPs detection system using C # language to design the control program of the sound card, and realizes the acquisition of the CAPs signal under the sound stimulation. The CAP threshold curve and tuning curve were obtained to characterize the function of auditory nervous system. The system provides a comprehensive and objective platform for the detection and follow-up study of the compound action potential of the auditory nerve.
