Recording EEG from the ear

A method for measuring electroencephalograms (EEG) from the outer ear, so-called Ear-EEG, has recently been proposed. Ear-EEG yields similar timing of event-related potential (ERP) components, similar time-frequency characteristics of spontaneous neural responses, and equal signal strength as that from conventional EEG for sources close to the ear. Ear-EEG can be measured from electrodes embedded on ear-pieces, and several practical implementations of Ear-EEG platforms, individualized as well as more generic, have been proposed.  Compared with existing on-scalp systems, the Ear-EEG platform has several attractive properties: it is discreet, it is comfortable to wear and unobtrusive, it is user-friendly and can be operated and attached by the user. Ear-EEG exhibits a high degree of comfort and excellent long term wearability; thus, at the expense of a limited spatial resolution, enable robust recordings of EEG in natural environments. This presentation will introduce the ear-EEG method, show various examples of ERPs related to the auditory system, and show examples of spontaneous neural responses.
