Our final Goal is to develop brain computer interfaces (BCIs) by the steady-state visual evoked potential (SSVEP).The BCI on SSVEP is used as a switching device. Therefore, many researchers do not focus on the SSVEP in long-term recordings. However, the SSVEP is not always generated in watching flashing visual stimuli. In this research, we focus on the SSVEP in long-term recordings and relationship between SSVEP and eye blink.In this research, we showed flashing visual stimuli. Frequencies of these stimuli are 15 and 20 Hz. Subjects are 3 males. The visual stimuli are shown during 60 [sec].As results, we confirmed that SSVEPs is not always generated and the power of SSVEPs has fluctuation. Next, we confirmed relationship between powers of SSVEPs and eye blink. In 1 [sec] later from eye blink, powers of SSVEPs increased more than the power before eye blink.
