Modality Difference in N2 and P3 Components Between Visual and Auditory Go/No-Go Paradigms

Abstract

Abstract. We investigated the modality difference in the N2 and P3 components of event-related potentials (ERPs) between visual and auditory Go/No-go paradigms. We evaluated the relationship between RT and the amplitudes and latencies of N2 and P3 in visual and auditory Go/No-go paradigms. No significant differences were observed in the latencies of N2 and P3 between visual and auditory paradigms. Significant correlations were observed between RT and the latency of P3 in the visual and auditory paradigms. In contrast, the amplitudes of N2 and P3 were significantly larger in the visual paradigm than in the auditory paradigm. A significant correlation was observed between RT and the amplitude of P3 only in the auditory paradigm. These results suggested that there were two neural networks for the response execution and inhibitory function, common and uncommon, that depended on the stimulus modality.
