Event-related potentials elicited by different complex patterns

Introduction: Stimulation with significant stimuli of any modality elicits event-related potentials (ERP). Different generators share the generation of these ERP. The aim of this study was to observe the accumulative activation of different generators of ERP according to the complexity of presented stimuli. Method: We examined 15 healthy subjects (7♀, 8♂), aged 27 (±1,7) years. ERP were elicited by three different black/white patterns of increasing complexity: i) a regular checkerboard, ii) an irregular checkerboard without any content, iii) an irregular checkerboard with an embedded letter. Black/white relation…
