Abstract

This paper presents a method for removing electroocular (EOG) artifacts in the electroencephalogram (EEG). The procedure is based on blind source separation (BSS) and, in contrast to methods already available in the literature, it is completely automated and does not require the availability of peri-ocular EOG electrodes. The proposed approach removed most EOG artifacts in 6 long-term EEG recordings containing epilectic seizures without distorting the recorded ictal activity
