N1 and P1 Components of the Visual Evoked Response in Humans. A Topographical and Functional Comparison.

Abstract

The N1 and P1 components of the visual evoked response (VER) in humans were compared along several dimensions. To elicit the VER, square-wave gratings were presented in pattern-appearance/disappearance and phase-reversal stimulation modes. The gratings varied in terms of contrast, spatial and temporal frequency, and the region of the visual field in which they were presented. The results of these experiments indicated that the N1 and P1 components of the human VER possess similar functional and topographical characteristics, and may reflect a common neural origin.
