中文简介:
使用数据驱动的时频分析来分析对音频刺激的大脑反应。 这是基于脑电图（EEG）记录和听觉啁啾或音乐作为音频刺激来实现的。 经验模式分解（EMD）应用于多通道EEG记录，并且通过分析听觉稳态响应（ASSR）的动态来提供对脑响应的洞察。 在对EEG对古典音乐的反应的分析中进一步说明了所提出的方法。 基于EMD和光谱图匹配技术的可视化提供了全面的同步分析。 仿真结果说明了该方法的潜力未来的大脑计算机/机器接口。
课程简介: Brain responses to audio stimuli are analysed using data driven time-frequency analysis. This is achieved based on the electroencephalogram (EEG) recordings and with auditory chirps or music as the audio stimulus. The empirical mode decomposition (EMD) is applied to multichannel EEG recordings, and the insight into the brain responses is provided by the analysis of the dynamics of auditory steady-state responses (ASSR). The proposed approach is further illustrated on the analysis of EEG responses to classical music. A comprehensive synchrony analysis is provided based on the visualization of EMD and spectrogrammatching techniques. Simulation results illustrate the potential of the proposed approach in future brain computer/machine interfaces.
