HIGH SPEED DIGITAL RECORDER FOR ACQUIRING ELECTROPHYSIOL

研究单个神经元已被证明对理解 它们的功能。然而，所有的生物系统都是由一个 与各种感觉和骨骼相互作用的大量神经元 肌肉系统。研究人员急于拥有记录的能力 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 已经发明了电极来研究大量分子之间的相互作用 神经细胞的。然而，为了记录所有的频道，研究人员 必须把几台录音机放在一起。这导致了在 在回放过程中准确匹配所有频道，因为 多台录像机联动的复杂性。R.C-电子公司建议 利用PC技术构建一款低成本、高速的数字录像机。 这台数字录音机将能够大量连续记录 总速率为1 MHz的存储设备。它还将提供 研究人员能够获取多达96个频道，每个频道 以10 kHz采样的通道；使用更少的资源即可实现更高的速度 频道。 建议的商业应用：市场对 数字记录仪在众多生命科学中的应用 在复杂的生物系统研究中。我们也相信，这将是 是一个很好的工业记录器，能够取代现有的模拟记录器 以及用于声学、噪声的DAT记录器。和振动研究。会有的 也被市场取代了一些基于高端工作站的 惠普、并发和Sun数据采集系统。

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.
