Measurement Method of Event-related Potential using Attention Trigger

Abstract

There should be close relationship between eye fixation and cognition to the images. Therefore, we used observer's eye movements as trigger for measurement of event related potentials (ERP). We investigated then related to the between eye fixation and properties of ERPs. As the result, the latency of ERPs obtained in attention trigger was shorter than it obtained in the electrooculography (EOG) or the stimulus triggers. This new technique suggests the way to reduce the latency of ERPs
