Visual evoked potentials to line- and luminance-defined triangles.
Full Abstract
Processing of line- and luminance-defined triangles was investigated by studying visual potentials (VEPs) evoked by triangles. Twenty-six subjects were randomly presented with line, grey, and illusory triangles. Relative to VEPs elicited by grey and illusory triangles, VEPs to line triangles included P220s that were smaller at frontal sites but larger at occipital sites, and N260s that were smaller over both temporal and occipital sites. It is proposed that, in contrast to triangle defined by a line, illusory and luminance-defined triangles include information involved in the processing of surface.
