From: A no-go related prefrontal negativity larger to irrelevant stimuli that are difficult to suppress
Grand-average (N = 26) ERP waveforms recorded at left occipito/temporal (P9), midline occipital/parietal (POz), precentral (FCz) and prefrontal (PFz) sites as a function of attention condition and independent of stimulus spatial frequency. ERPs elicited by real targets (the extreme frequencies 0.75 and 6 c/deg) are in black, whereas the ERPs elicited by lures are in colour. The only component elicited by pseudo-targets that did not clearly indicate targetness was the prefrontal N3 deflection.
