EOG校正是一类通过从EEG中减去眼电图数据来解释EEG中的眼伪影的技术。本研究的目的是评估其中四种矫正技术（Verleger，Gasser，& Mocks，1982 [VGM]; Gratton，Coles，& Donchin，1983 [GCD]; Semlitsch，Presslich，Schuster，& Anderer，1986 [SPSA]; Croft &巴里，2000 [CB]）。眨眼，垂直眼球运动（VEM），水平眼球运动（HEM）从26名受试者使用这些技术进行了纠正，并计算眼动事件相关电位，以帮助验证。通过CB、VGM/GCD然后SPSA更好地校正HEM，通过CB、VGM/GCD然后SPSA更好地校正VEM，并且通过CB、SPSA、GCD然后VGM更好地校正眨眼，其中CB对于眨眼（eta（2）> 0.72）、VEM（eta（2）> 0.60）和HEM（eta（2）> 0.27）具有显著的优势。有人认为，CB程序充分考虑到EEG中的眼伪影。其他程序的局限性的原因进行了讨论。
EOG correction is a class of techniques that account for ocular artifact in the electroencephalogram (EEG) by subtracting electrooculographic data from the EEG. The purpose of this study was to evaluate four of these correction techniques (Verleger, Gasser, & Mocks, 1982 [VGM]; Gratton, Coles, & Donchin, 1983 [GCD]; Semlitsch, Presslich, Schuster, & Anderer, 1986 [SPSA]; Croft & Barry, 2000 [CB]). Blinks, vertical eye movements (VEM), and horizontal eye movements (HEM) from 26 subjects were corrected using these techniques, and eye movement event-related potentials computed to aid validation. HEMs were corrected better by CB, VGM/GCD then SPSA, VEMs by CB, VGM/GCD then SPSA, and blinks by CB, SPSA, GCD and then VGM, with the advantage of CB substantial for blinks (eta(2) >.72), VEMs (eta(2) >.60), and HEMs (eta(2) >.27). It is argued that the CB procedure adequately accounts for ocular artifact in the EEG. Reasons for the limitations of the other procedures are discussed.
