Abstract

The auditory steady state evoked response (ASSR) is a robust and frequently utilized phenomenon in psychophysiological research. It reflects the auditory cortical response to an amplitude-modulated constant carrier frequency signal. The present report provides a concrete example of a group analysis of the EEG data from 29 healthy human participants, recorded during an ASSR paradigm, using the FieldTrip toolbox. First, we demonstrate sensor-level analysis in the time domain, allowing for a description of the event-related potentials (ERPs), as well as their statistical evaluation. Second, frequency analysis is applied to describe the spectral characteristics of the ASSR, followed by group level statistical analysis in the frequency domain. Third, we show how time- and frequency-domain analysis approaches can be combined in order to describe the temporal and spectral development of the ASSR. Finally, we demonstrate source reconstruction techniques to characterize the primary neural generators of the ASSR. Throughout, we pay special attention to explaining the design of the analysis pipeline for single subjects and for the group level analysis. The pipeline presented here can be adjusted to accommodate other experimental paradigms and may serve as a template for similar analyses.

摘要

听觉稳态诱发反应(ASSR)是心理生理学研究中一种强大且常用的现象。它反映了听觉皮层对调幅恒定载波频率信号的反应。本报告提供了一个具体示例,展示了使用FieldTrip工具箱对29名健康人类参与者在ASSR范式期间记录的脑电图(EEG)数据进行组分析的过程。首先,我们展示了时域中的传感器级分析,可用于描述事件相关电位(ERP)及其统计评估。其次,应用频率分析来描述ASSR的频谱特征,随后在频域进行组水平统计分析。第三,我们展示了如何结合时域和频域分析方法来描述ASSR的时间和频谱发展。最后,我们展示了源重建技术,以表征ASSR的主要神经发生器。在整个过程中,我们特别关注解释单受试者和组水平分析的分析流程设计。这里介绍的流程可以进行调整以适应其他实验范式,并可作为类似分析的模板。
