of the P300 amplitude, documented in several EEG studies (Barry et al., 2000; Croft et al., 2003; Gonsalvez and Polich, 2002), might be considered an electrophysiological correlate of ongoing adaptive processes associated with target detection. In addition, other neuroimaging studies provided evidence for the existence of the core network, a functional system dedicated to stable task control and primarily including insula and anterior cingulate cortex (Dosenbach et al., 2006, 2007), which can be assumed to be engaged during target detection as well.
