Stimulus repetition and an amplitude increase of the occipital late positive component in the human visual evoked potential

Effects of brief stimulus duration on the amplitude of the occipital late positive component associated with verbal and non-verbal tasks

“…These P260 amplitude changes across positions in 50 ms session seem to coincide with the findings reported by Kitajima et al(1980Kitajima et al( , 1983 in which they demonstrated larger amplitude of the P260 (P270 in their papers) at late stimulus positions using stimulus duration of 300 ms. The P260 amplitude changes in 25 ms session seem to coincide with the findings reported by Kitajima et al(1981) in which they demonstrated large amplitude at stimulus position 1 and small amplitude at stimulus positions 2-3 using stimulus duration of a fraction of a millisecond or 10ms.…”
