Implication

Experimental study demonstrates reliable neural recording via outer ear electrodes across auditory paradigms, highlighting ear-EEG as a viable alternative for naturalistic monitoring.

Key Points

To evaluate the validity and signal fidelity of outer ear EEG recordings compared with conventional scalp EEG across multiple auditory and frequency-based paradigms.
Simultaneously recorded electroencephalograms using 32 conventional scalp electrodes and 12 outer ear electrodes across varied reference configurations.
Evaluated four neural paradigms: auditory onset response, mismatch negativity, auditory steady-state response, and alpha power attenuation.
Ear electrodes demonstrated matching signal-to-noise ratios to nearby scalp electrodes and preserved the timing of event-related potential components.
Auditory steady-state responses and alpha-band modulations were recorded reliably, whereas the auditory mismatch negativity response was difficult to monitor.
