Frequency Band Separation of Neural Rhythms for Identification of Eog Activity from Eeg Signal

The identification of EOG activity from the electroencephalogram (EEG) recorded from the parietal occipital region is analysed. The occurrence of ocular biosignals from scalp EEGs is mandatory for both the automated and visual analysis of underlying brainwave activity. The most prominent eye-induced artefacts are caused by the potential difference between the cornea and retina, which is quite large compared to cerebral potentials. As the occipital region of the brain is concerned with the potentials related to the vision, the EEG potentials recorded from occipital parietal lobe is analysed for EOG signal after frequency band separation.
