Should We Really Use Different Estimates for Correcting EEG Artefacts Produced by Blinks and by Saccades?

have published a careful study on the propagation of ocular potentials to the EEG. Based on their findings in overall 80 subjects they strongly recommend estimating the transmission of ocular potentials to the EEG sepa-rately for blinks and vertical saccades, in order to remove these artefacts appropriately from the measured EEG. Based on these same findings, I will continue to use one and the same transmission coefficient for correcting the artefacts of blinks and vertical saccades. My reasoning is as follows. 1. Differences in the transmission of ocular potentials were found by Picton et al. (2000) between blinks and upward saccades only – not between blinks and down-ward saccades. This means that artefacts caused by downward saccades are adequately removed by using
