In the present paper, we describe and validate a computerized system for the quantitative analysis of colonic spike activity in the conscious rabbit. This system allowed data acquisition at 160 Hz on 8 channels simultaneously during the recording session. Data analysis at the end of the recording session took approximately 10 min for each hour of recording. The spike recognition procedure was carried out on the basis of a discriminant function which discarded artifactual fast events. Data could be presented as histograms or be transferred into an ASCII file for later statistical analysis. Reliability tests showed that the misrecognition rate was only 3.88%. In conclusion, this computerized system is a reliable, timesaving tool for the quantitative analysis of colonic spike activity.
在本论文中，我们描述并验证了一种用于定量分析清醒家兔结肠锋电位活动的计算机系统。该系统在记录过程中能够以160赫兹的频率同时采集8通道的数据。记录结束后，每小时的记录数据分析大约需要10分钟。锋电位识别程序基于一个判别函数进行，该函数可剔除人为产生的快速事件。数据可以以直方图形式呈现，或者被转换为ASCII文件以便后续进行统计分析。可靠性测试表明，误识别率仅为3.88%。总之，这种计算机系统是用于结肠锋电位活动定量分析的一种可靠且省时的工具。
