Abstract :
Eye-Fixation Related Potentials technique is a joint analysis of both electrical brain activities and ocular movements. It allows to extract neural components synchronized with ocular fixations. However, the extracted brain responses, elicited by adjacent fixations, can be distorted by overlapping processes due to short inter fixations intervals. In this work, the ability of two algorithms, Adjar and xDawn are compared to correct these distortions. The Adjar algorithm is based on assumptions regarding the temporal distributions which become too restrictive for EFRP studies. On the hand, the xDawn algorithm is based on a more general and flexible model that is better adapted for EFRP studies.
