用于音乐治疗的人体脑电检测系统设计

本文介绍了一种基于音乐治疗的人体脑电信号采集和处理系统，该系统可以对人在音乐治疗前后的脑电信号进行采集、处理和分析。系统的检测电极从人的脑部采集信号，通过预处理电路传到单片机控制模块，再采用nRF24L01无线通信模块将采集到的信号传给上位机，上位机程序对脑电信号进行处理、分析、显示。实验表呀，系统能够较好的获取人体脑电信号，数据处理结果显示，有音乐刺激时的脑电信号和无音乐刺激时的脑电信号相比，信号幅值增大、复杂度降低。

Human EEG Detection System Design For Music Therapy

This paper introduces an EEG signal acquisition and processing system based on the system of music therapy, for processing and analysis of EEG signal acquisition in music therapy. The detection electrode collects signal from the brain, the signal passed to control module through the pretreatment circuit, then to the host computer using the nRF24L01 wireless communication module. The host computer program processes, analyzes, and displays the EEG signals. Experiments show that the system can better access to human EEG data. Processing results show that comparing the EEG with music stimuli to those without music stimuli, the amplitude of the signal is increased, and the complexity is reduced.
