Investigating individual neurons has proven very useful in understanding their functionality. However, all biological systems are composed of a multitude of neurons that interact-with a variety of sensory and skeletal muscular systems. Researchers are anxious to have the ability to record a large number of neuron firing patterns to study how they communicate and interact in a biological system. Tools such as the multi-channel electrode have been created to study the interactions of large numbers of neurons. However, in order to record all the channels, the researcher must gang several recorders together. This leads to difficulties in accurately matching all the channels during playback, because of the complexity of ganged multiple recorders. R.C - Electronics Inc. proposes to build a low cost, high speed digital recorder utilizing PC technology. This digital recorder will be able to record continuously to a mass storage device at an aggregate rate of 1 MHz. It will also provide the researcher with the ability to acquire up to 96 channels, with each channel sampled at 10 KHz; higher speeds will be possible with fewer channels. PROPOSED COMMERCIAL APPLICATION: There is a market demand for the digital recorder in the multitude of life science applications engaged in complex biological system studies. We also believe that this will be a good industrial recorder, capable of replacing the existing analog and DAT recorders for acoustic, noise. and vibration studies. There will also be a market to replace some of the high-end work stations based on HP, Concurrent and Sun data acquisition systems.

研究单个神经元已被证明对理解 他们的功能。 然而，所有的生物系统都是由 大量的神经元相互作用-与各种感觉和骨骼 肌肉系统 研究人员渴望有能力记录 大量的神经元放电模式来研究它们是如何交流的 并在生物系统中相互作用。 多通道等工具 电极被用来研究大量的 的神经元。 然而，为了记录所有的渠道，研究人员 必须把几台录音机连在一起。 这导致了以下困难： 在播放过程中准确匹配所有通道，因为 联动多个记录器的复杂性。R.C. - Electronics Inc.提出 利用PC技术构建低成本、高速的数字记录器。 这台数字录音机将能连续记录大量的数据 存储设备以1 MHz的聚合速率。 它还将提供 研究人员能够获得多达96个通道，每个通道 通道采样频率为10 KHz;速度更高， 渠道 建议的商业应用：市场对 数字记录仪在众多生命科学应用中的应用 在复杂的生物系统研究中。 我们还认为， 是一个很好的工业记录仪，能够取代现有的模拟 和DAT录音机的声音，噪音。振动研究。 会 也是一个市场，以取代一些高端工作站的基础上， HP、Concurrent和Sun数据采集系统。
