最近提出了一种基于耳内电极测量脑电（EEG）的脑监测方法。本研究的目的是进一步表征耳EEG，并与传统的头皮EEG进行严格的比较。这是实现听觉和视觉诱发反应，在稳态和瞬态范例，并在整个人口的主题。各自的稳态响应进行评估的信噪比和统计意义，而瞬态响应的定性分析是通过考虑总平均事件相关电位（ERP）波形。这项研究的结果最终表明，耳朵EEG信号，在信噪比方面，与传统的EEG记录从放置在颞区的电极。
A method for brain monitoring based on measuring the electroencephalogram (EEG) from electrodes placed in-the-ear (ear-EEG) was recently proposed. The objective of this study is to further characterize the ear-EEG and perform a rigorous comparison against conventional on-scalp EEG. This is achieved for both auditory and visual evoked responses, over steady-state and transient paradigms, and across a population of subjects. The respective steady-state responses are evaluated in terms of signal-to-noise ratio and statistical significance, while the qualitative analysis of the transient responses is performed by considering grand averaged event-related potential (ERP) waveforms. The outcomes of this study demonstrate conclusively that the ear-EEG signals, in terms of the signal-to-noise ratio, are on par with conventional EEG recorded from electrodes placed over the temporal region.
