“…The fact that the P3a reflects non-voluntary (automatic, Muller-Gass et al, 2007) processes is indicated by the fact that the P3a can be elicited (although with reduced amplitude) during deep propofol sedation, i.e. when subjects are not consciously aware of unexpected events (Koelsch et al, 2006).…”

“…Response to targets is associated with a prominent P3b component maximal over parietal regions, while novel distractors evoke a prominent frontocentral P3a component (Muller-Gass et al 2007;Polich 2007;Squires et al 1975). However, both P3a and P3b can occur in response to either targets or distractors (Katayama and Polich 1999;Sawaki and Katayama 2007;Turetsky et al 1998a).…”

“…der "Error Related Negativity" (ERN) (Roeber et al, 2003 (Courchesne et al, 1975). Eine P3a auf überraschende akustische Signale wird auch dann beobachtet, wenn die Aufmerksamkeit voll durch eine schwierige visuelle Aufgabe in Anspruch genommen ist, d. h., dass es sich ähnlich wie bei der MMN um eine automatische und unbewusste Reaktion handelt (Muller-Gass, et al, 2007). Die P3a wird als neurophysiologisches Korrelat einer unwillkürlichen Aufmerksamkeitszuwendung, einer latenten Orientierungsreaktion, aufgefasst (Liu et al, 2007 (Cowan, et al, 1993;Ritter et al, 2002) bzw.…”
