The research adopts the classical visual evoked potentials paradigm, designs the stimulation program and experimental scheme base on the labview platform,and the way of visual stimulate is studied in this paper.In this way we can produce event-related potentials more effectively . On the platform in labview,achieve the event-related potential signal acquisition and processing.Explore how extract the weak signal event-related potentials in the background of strong noise rapidly and accurately,and structures based on event-related potentials of the brain machine interface platform.
