A 2-channel action-potential generator system was designed for use in testing neurophysiologic data acquisition/analysis systems. The system consists of a personal computer controlling an external hardware unit. This system is capable of generating 2 channels of simulated action potential (AP) waveshapes. The AP waveforms are generated from the linear combination of 2 principal-component template functions. Each channel generates randomly occurring APs with a specified rate ranging from 1 to 200 events per second. The 2 trains may be independent of one another or the second channel may be made to be excited or inhibited by the events from the first channel with user-specified probabilities. A third internal channel may be made to excite or inhibit events in both of the 2 output channels with user-specified rate parameters and probabilities. The system produces voltage waveforms that may be used to test neurophysiologic data acquisition systems for recording from 2 spike trains simultaneously and for testing multispike-train analysis (e.g., cross-correlation) software.
设计了一种双通道动作电位发生器系统，用于测试神经生理数据采集/分析系统。该系统由一台控制外部硬件单元的个人计算机组成。该系统能够生成2通道的模拟动作电位（AP）波形。AP波形由2个主成分模板函数的线性组合生成。每个通道以每秒1至200个事件的指定速率生成随机出现的AP。这两列波可能彼此独立，或者第二个通道可以按照用户指定的概率被第一个通道的事件激发或抑制。第三个内部通道可以按照用户指定的速率参数和概率激发或抑制两个输出通道中的事件。该系统产生的电压波形可用于测试神经生理数据采集系统，以便同时记录2个脉冲序列，并用于测试多脉冲序列分析（如互相关）软件。
