The purpose of research is to investigate a processing of visual information and motion control. In order to investigate brain function of vision and motion, we are going to measure MEG (magneto encephalography) under condition in which visual stimulus are applied. MEG has a high temporal resolution, but MEG is sensitive to magnetic noise. Therefore, experimental conditions and stimulation system are restricted in MEG. Considering MEG's advantage and disadvantage, we developed visual stimulation system, which can be used with MEG. In this paper, we reported a test of magnetic noise from this visual stimulation system, and a influence of eye movement by measuring EOG (electroculogram).
