From spatial frequency contrast to edge preponderance: the differential modulation of early visual evoked potentials by natural scene stimuli
Explore this paper's citation graph
Summary
The results suggest that the relative dominance in signal output of the N1 and P1 components is dependent on spatial frequency (SF) luminance contrast for simple stimuli up to natural scene imagery possessing few edges, however, such a dependency shifts to a dominant N1 signal for natural scenes possessing abundant edge content and operates independently of SF luminance Contrast.
