“…In response inhibition tasks it is larger in amplitude on no-go trials as well as successful stop trials (Enriquez-Geppert et al, 2010;Fallgatter & Strik, 1999;Smith, Johnstone, & Barry, 2007) and has a more frontal topography (termed 'no-go anteriorisation, NGA) (Fallgatter, Brandeis, & Strik, 1997;Fallgatter & Strik, 1999), potentially reflecting activity in pre-SMA and inferior frontal cortex (Huster et al, 2011) or cingulate regions (Fallgatter, Bartsch, & Herrmann, 2002;Strik, Fallgatter, Brandeis, & Pascual-Marqui, 1998). This has led to the suggestion that in the context of action regulation, the P3 is a marker of response inhibition with some authors proposing it as a more reliable marker of response inhibition than the N2 8 (Kropotov, Ponomarev, Hollup, & Mueller, 2011;Meel, 2005;Randall & Smith, 2011;Smith et al, 2007).…”
