论文摘要
在现实世界中，EAR-EEG已成为可穿戴大脑监测的有前途的候选人。尽管实验研究已经验证了多种情况下的EAR-EEG，但尚未建立各种神经来源的源传感器关系。此外，仍然缺少对EE-EEG对伪影来源的敏感性的详细理论分析。在本研究中，除了眨眼，垂直扫视和水平扫视眼动眼动物外，EAR-EEG各种构型的敏感性是在神经源的存在下建立的。结果最终支持将EAR-EEG引入常规的EEG范式中，以监测源自颞叶内部的神经活动，同时还揭示了可以将EAR-EEG用于远离这些区域的源的程度。通过分析ear-eeg的眼部伪像的突出性，支持了远离耳朵的源的EAG的使用。这项研究的结果可用于在神经和眼部伪影敏感性的背景下支持现有和前瞻性的实验EAGEEG研究和应用。
The ear-EEG has emerged as a promising candidate for wearable brain monitoring in real-world scenarios. While experimental studies have validated ear-EEG in multiple scenarios, the source-sensor relationship for a variety of neural sources has not been established. In addition, a detailed theoretical analysis of the ear-EEG sensitivity to sources of artifacts is still missing. Within the present study, the sensitivity of various configurations of ear-EEG is established in the presence of neural sources from a range of brain surface locations, in addition to ocular sources for the blink, vertical saccade, and horizontal saccade eye movements which produce artifacts in the EEG signal. Results conclusively support the introduction of ear-EEG into conventional EEG paradigms for monitoring neural activity that originates from within the temporal lobes, while also revealing the extent to which ear-EEG can be used for sources further away from these regions. The use of ear-EEG for sources that are located further away from the ears is supported through the analysis of the prominence of ocular artifacts in ear-EEG. The results from this study can be used to support both existing and prospective experimental ear-EEG studies and applications in the context of both neural and ocular artifact sensitivity.
