脑-机接口中脑波的拾取及滤噪的研究

Research of the methods for EEG signals detection and noise overcoming

脑-机接口(BC I)是在人脑和计算机或其他电子设备之间建立的一种直接信息交流和控制通道,是一种不依赖于常规大脑输出通路(外周神经和肌肉组织)的全新信息交流系统.BC I作为一种全新的信息交换与控制技术,将能为瘫痪病人,特别是那些丧失了基本肢体运动功能但思维正常的患者,提供一种与外界进行信息交流与控制的新途径,正受到越来越广泛的关注.脑-机接口中脑波的拾取及滤噪是其重要的环节,本文对脑-机接口中拾取脑波及干扰克服的方法进行了研究和分析.

Brain-computer interface （BCI） is a direct information communication and control channel established between human and computer or other electrical devices and it is a wholly new communication system that does not depend on the brain＇ s normal output pathways of peripheral nerves and muscles. As a novel information communication and control technology, EEG-based BCI may provide the paralyzed, especially those ＂locked-in＂ but with intact ideation, with an effective communication and control channels with outside world. That＇s why BCI is winning more and more attentions. This article analyses the methods for EEG signals detection and noise overcoming.
