Visual Illusion and N1 and P1: ERP Evidence
Yuki Todo, Wei Chen, Hongsuo Tang

Abstract
Recently, the brain science has become one of most attractive and important fields in modern science and technology. As the foundation of brain science, visual study of brain attracts researchers more attentions due to its wide applications, including psychology, biology and computer science. In the paper, we construct an experiment that uses the abutting line grating illusion contour stimulus with different number of lines, so that some perceive illusion contours and some do not. Event-related potentials (ERP) involving N1, P1 and power spectra are measured and compared to examine the difference of them when visual illusion stimuli and control stimuli are applied.
