中文摘要：
研制了一种生物神经电信号检测系统。该检测系统采用微丝电极作为信号采集传感器,经过微弱信号调理仪器对微弱神经信号进行放大、滤波等处理,开发基于Lab VIEW的上位机软件对所采集的信号进一步分析、显示以及存储等。实验中仪器噪声小于20μV的条件下检测到了幅值为160μV神经电信号,S/N≈8,结果表明：本检测系统可实现对微弱神经电信号的检测。
英文摘要：
A neuro-electrical signal detection system is researched and faricated. The system uses self-made micro-wire electrode as signal acquisition sensor, amplification and filtering are carried out on weak neuro- electrical signal is realized by weak signal conditioning instrument, upper PC software is developed based on LabVIEW to achieve further analysis, display, and storage of the collected signals. In experiment, 160 μV neuroelectrical signal is detected in condition of less than 20 μV noise, signal-to-noise （ S/N ） ratio is about 8. Experimental results show that the detection system can be used for weak neural-electrical signal detection.
