 Abstract: Eye-movements can result in large artifacts in the EEG signal that could potentially obscure weaker cortically-based signals. Therefore, EEG studies are typically designed to minimize eye-movements [although see, Plöchl et al., 2012; Dimigen et al., 2011]. We present methods for simultaneous EEG and eye-tracking recordings in a visual scanning task. Participants were required to serially attend to four area-of-interests to detect a visual target. We compare EEG results, which were recorded either in the presence or absence of natural eye-movements. Furthermore, we demonstrate how natural eye-movement fixations can be reconstructed from the EOG signal, in a way that is comparable to the input from a simultaneous video-based eye-tracker. Based on these fixations, we address how EEG data can be segmented according to eye-movements (as opposed to experimentally timed stimuli). Finally, we explain how eye-movement induced artifacts can be effectively removed via independent component analysis (ICA), which allows EEG components to be classified as having either a 'cortical' or 'non-cortical' origin. These methods offer the potential of measuring robust EEG signals even in the presence of natural eye-movements.
