Characterization of auditory steady state brain responses in time, frequency and space

The auditory steady state evoked response (ASSR) is a robust and frequently utilized phenomenon in psychophysiological research. It reflects the auditory cortex excitability as a response of a frequency modulated auditory stimulus. The present report aims to provide an example of a group analysis in 29 healthy human participants in the context of an ASSR paradigm. First, analysis in the time domain will demonstrate descriptive evaluation and statistical control of auditory event-related potentials (ERPs). Second, frequency analysis is applied to describe the spectral characteristics of these ERPs followed by group level statistics in the frequency domain. Third, time and frequency domain data approaches are combined in order to describe the temporal and spectral development of the ASSR. Finally, an example of analysis in source space is applied in order to characterize the primary neural generators of the ASSR response.

听觉稳态诱发电位（auditory steady state evoked response, ASSR）是心理生理学研究中一种稳健且常用的现象。其作为调频听觉刺激的响应，可反映听觉皮层的兴奋性水平。本数据集旨在提供一个基于ASSR范式、针对29名健康人类受试者的组分析示例。首先，时域分析将完成听觉事件相关电位（auditory event-related potentials, ERPs）的描述性评估与统计控制；其次，通过频谱分析刻画此类事件相关电位的频谱特征，并开展频域的组水平统计检验；再者，结合时域与频域分析方法，阐释ASSR的时域与频域动态演化规律；最后，通过源空间分析示例，表征ASSR响应的核心神经起源。本数据集包含所有可复现该论文中所呈现结果的原始数据与分析脚本。
