摘要
分析动物行为活动中的脑电特征是脑机接口(Brain-computer interface,BCI)研究中的一个重要内容。本文利用最新测控软件-虚拟仪器技术(LabVIEW)进行脑电信号采集与处理,实现了信号实时显示、中值滤波、小波消噪的设计。实验结果显示提取出了与特定行为(抓食)相关的脑电活动特征信号,为研究大脑如何控制行为提供了一个有效的方法。
In the study of BCI, the significant requirement is to analyze the characteristic neuronal activity in freely behaving small animals. In this paper, we use the latest monitoring software-Virtual Instrument （LabVIEW） for EEG signal acquisition and processing, to achieve these designs, including the real-time display, median filtering and wavelet denoising. Experimental results show that the operator extracted characteristic brain signals which was connected with behavior, and this system supplied a method to research how brain to control behavior.
