Description

Among functional brain scanning methods, electroencephalography (EEG) is the most promising method for non-invasive brain monitoring in real-life environments. Ear-EEG is a method where signals are recorded from electrodes placed on an earpiece inserted into the ear. The compact and discreet nature of ear-EEG devices makes it suitable for long-term real-life recordings. In this study, EEG were recorded from 6 subjects with conventional scalp EEG and dry-contact ear-EEG. All recordings were performed with the same instrumentation and paradigms in both a lab setting and a real-life setting. The study comprised four paradigms: auditory steady-state response (ASSR), steady-state visual evoked potential (SSVEP), auditory onset response, and alpha band modulation. For both settings, the investigated responses were observable and statistically significant (p<0.05) in recordings from ear-electrodes referenced to a scalp electrode (Cz). Statistically significant ASSR and SSVEP were measured in the lab setting by ear-electrodes referenced to an electrode within the same ear. In the real-life setting, only the ASSR was statistically significant for a reference within the same ear. The results demonstrates that ear-EEG recordings can be performed with dry-contact electrodes in real-life.
