A simple technique for eye blink correction

Abstract

The ability to correct for ocular artifacts in EEG signals recorded during the course of event-related potential experiments is of major importance. The basic principle used when correcting ERP's with recorded EOG signals is to consider the ocular artifacts as a linear combination of the measured EOG signals and to subtract these ocular artifacts from the measured ERP signals. This pcrper describes a simplified method for calculating EOG correction coefficients for eye blinks. Preliminary resu l t s of applying this technique to the EEG data of seven children have shown a significant increase in the number of usable trials available for computing averages.
