Ear-EEG Recording for Brain Computer Interface of Motor Task

Ear-EEG recording collects brain signals from electrodes placed in the ear canal. Compared with existing scalp-EEG, ear-EEG is more wearable and user-comfortable compared with existing scalp-EEG. In this dataset, we collected ear-EEG signals and the scalp-EEG signals when subjects were performing a left/right hand grasping motor task. We first validated the ear-EEG recordings by measuring the similarity of power ratio and channel correlation between ear-EEG and scalp-EEG signals. Then we applied EEG compact network (EEGNet) for classification of left/right-hand motor tasks using ear-EEG signals and scalp EEG signals separately. Our results showed motor task classification based on ear-EEG has a high potential for the practical BCI applications in motor task.
