Ear-EEG Sleep Monitoring 2023 (EESM23): at-home sleep recordings from 10 healthy participants by an Aarhus University group, each with two nights of combined ear-EEG and polysomnography followed by ten ear-EEG-only nights, using generic ear pieces with dry electrodes. Released on OpenNeuro as ds005178 (CC0) and described in Scientific Data (2025).

Fewer electrodes · in-ear vs. scalp sleep staging

Read with its protocol: Fewer electrodes · Chance level 20.0% · evidence-update.json

Log-bandpower logistic regression · Four in-ear channels

53.6% (47.4%–59.7%)

Log-bandpower logistic regression · Six scalp electrodes

69.0% (63.4%–74.2%)

Balanced accuracy, 2 configurations. Dot: the estimate; line: 95% interval; dashed line: chance level where the payload records one.
