N2 event-related potential correlates of response inhibition in an auditory Go/Nogo task

Int J Psychophysiol. 2006 Aug;61(2):279-82. doi: 10.1016/j.ijpsycho.2005.09.006. Epub 2005 Nov 17.


The aim of this study was to investigate the event-related potential correlates of response inhibition in the N2 time window, specifically in the auditory modality. A paired tone Go/Nogo paradigm elicited an enhanced fronto-central negativity in the Nogo condition, which was accompanied by a concurring inferior fronto-temporal positivity. In contrast to most previous studies our data provide evidence for a fronto-central Nogo-N2 component in the auditory modality.
