摘　　要：神经反馈技术是一种可供选择的行为学治疗手段,是将脑电(EEG)信号转换成容易被人们理解的声音、动画等形式,受试者通过训练,选择性地增强或抑制某一频段的EEG信号,可以达到调节脑功能的目的。本文基于脑-机接口技术,从实时EEG信号中提取特征参数并产生反馈信息,针对放松训练和注意力训练设计了两个反馈界面,搭建了一套完整的神经反馈系统。通过系统仿真和初步实验,验证了本套神经反馈系统的准确性和可行性。Neurofeedback, as an alternative treatment method of behavioral medicine, is a technique which translates the electroencephalogram （EEG） signals to styles as sounds or animation to help people understand their own physical status and learn to enhance or suppress certain EEG signals to regulate their own brain functions after several repeated trainings. This paper develops a neurofeedback system on the foundation of brain-computer interface technique. The EEG features are extracted through real-time signal process and then translated to feedback information. Two feedback screens are designed for relaxation training and attention training individually. The veracity and feasibility of the neurofeedback system are validated through system simulation and preliminary experiment.
