基于LabVIEW的脑电信号采集与处理系统

A Brain Electrical Signal Collecting and Processing System Based on LabVIEW

将现代虚拟仪器技术与集成电路技术结合设计了一种脑电活动信号采集与处理系统,包括自制金属电极和微驱动器、信号采集模拟前端、数字示波器,并以LabVIEW作为计算机编程语言的信号处理与显示界面。结果显示,系统能记录和分析鼠在清醒、自由活动状态下运动时的脑电活动信号,从而提供脑电活动和行为的关联性。这对于神经科学与信息技术学科交叉研究有十分重要的意义。

An electrophysiological signal collecting and progressing system is designed combining with modern virtual instrument and integral circuit technique including the metal chronic electrode made by ourselves, the micro-driver assembly and the digital oscillography and,also the LabVIEW is taken as the signal processing and display interface for the computer coding language. The results sbow that this system is able to record and analyze the brain electrical signal while rats move consciously and freely, which provides the possibility of studying the relationship between brain and behavior. This is very important for the study of the interdisciplinary research of neuroscience and information technique.
