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…

EEG Recorded from the Ear: Characterizing the Ear-EEG Method
TLDR
Ear-EEG yields similar performance as conventional EEG for spectrogram-based analysis, similar timing of ERP components, and equal signal strength for sources close to the ear, and the auditory mismatch response was difficult to monitor with the ear- EEG.

TLDR
High-density ear-EEG can be used to investigate how different cortical sources maps to the ear, and provides a way to select optimal electrode positions for given brain phenomena.
Reference configurations for ear-EEG steady-state responses
TLDR
This work presents a method for optimizing the reference configuration for steady-state type potentials, and demonstrates a robust SNR estimate, yielding on par or better SNR compared to other well-known methods.

TLDR
It is demonstrated thatEar-EEG can be used to develop an endogenous BCI system based on cognitive tasks without external stimuli, which allows the usability of ear-EEGs to be extended.
Physiological artifacts in scalp EEG and ear-EEG
TLDR
Ear-EEG was more prone to jaw related artifacts and less prone to eye-blinking artifacts compared to state-of-the-art scalp based systems, and spontaneous activity, in terms of alpha band oscillations, could be recorded from the ear- EEG platform.
Auditory Steady-State Responses Across Chirp Repetition Rates For Ear-EEG And Scalp EEG
TLDR
In this study, ASSRs were recorded using both scalp and ear-EEG in response to broadband chirp stimuli with repetition rates from 20 to 95 Hz and the results showed that use of relatively high repetition rates may be beneficial in earEEG applications.

Event-Related Potentials Measured From In and Around the Ear Electrodes Integrated in a Live Hearing Device for Monitoring Sound Perception
TLDR
Results confirm that meaningful brain signals related to the settings of a hearing device can be acquired from ear-EEG during real-time audio processing, particularly if electrodes around the ear are available.
Dry-Contact Electrode Ear-EEG
TLDR
The study demonstrated that dry-contact electrode ear-EEG is a feasible technology for EEG recording, and represents an important technological advancement of the method in terms of user-friendliness, because it eliminates the need for gel in the electrode-skin interface.
