摘要: The aim of this study was to investigate whether the amplitude gamma-band activity is influenced by factor age. We examined alpha- and EEG event-related potentials (ERPs) 12 subjects. Six subjects constituted younger (mean age=36.6 years) another six older age group age=47.6 years). Subjects performed a visual discrimination task which required response Kanizsa squares (targets) among Kanizsa-triangles non-Kanizsa figures. ERPs revealed significantly larger N 170 amplitude. amplitudes evoked were also found be higher in group. discuss implications these findings possible reasons for change oscillatory
