Using the N1 Potential for the Analysis of the 2D Optical Illusion Stimulus

Vol. 12  No. 9  pp. 55-58


Recently, the brain science has become one of most attractive and important fields in modern science and technology. Several centuries ago the overarching obstacle in the evolution of vision, especially the visual illusion was documented when George Berkeley pointed out that information in retinal images cannot be mapped unambiguously back onto their real-world sources. In this 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 and power spectra are measured and compared to examine the difference of them when visual illusion stimuli and control stimuli are applied.
