A Review of EEG-Neurofeedback

摘要

脑电神经反馈是一种基于脑电图的无创大脑刺激形式，通过脑机接口把从个体大脑中提取的电生理活动特征以实时反馈刺激的形式呈现给个体，使个体在反馈刺激的强化作用下学习自我调节大脑活动。脑电神经反馈能够应用于异常精神障碍的辅助治疗，健康个体认知功能表现的提升以及作为实验条件探究电生理特征与认知功能的交互作用。本研究从反馈系统的组成部分、实验设计的要素、训练效果评估以及机制作用等四个方面对脑电神经反馈进行综述，使读者对脑电神经反馈有一个清晰的认知。 Based on the technology of electroencephalography, EEG-Neurofeedback is a noninvasive method for brain stimulation. Through the brain-computer interface for delivering the signals of electro-physiological activity from brain to computer, EEG-Neurofeedback represents the real-time varia-tion of the activity above as the feedback stimulations to participants themselves to assist them to learn how to regulate the brain activities themselves. EEG-Neurofeedback has broad application that consisted of the adjuvant therapy for mental disorders, cognitive performance improvement for healthy individuals as well as acting as the experimental condition for the interactions between electrophysiological features of the brain and cognitive functions. To make a clear understanding of EEG-Neurofeedback, this article review it from four parts consisting of the component parts of EEG-Neurofeedback system, the elements for designing an EEG-Neurofeedback protocol, the evaluation of the EEG-Neurofeedback as well as the mechanism theories of EEG-Neurofeedback.
