| Event-related potentials | DMN attentional activity | Attentional modulation |
|---|---|---|
| P3 | Temporal-parietal activity | Sustained attention |
| N2pc | Posterior-contralateral activity related distractor positivity (P) | Selective attention and altered cognitive processing |
| N1 | Short-lived audiovisual mismatch negativity (MMN) | Automatic attentional shifting |
| P3 – positive-deflected wave 3; N2pc – negative-deflected posterior-contralateral wave 2; N1 – negative-deflected wave 1; DMN – default mode network. | ||
