However, unlike children and adolescents, individuals with psychiatric conditions related to impulsiveness, including alcoholism have consistently been found to have lower power of slow waves (time-locked to the events) while performing a behavioral or cognitive task compared to controls (Andrew and Fein, 2010, Jones, Porjesz, 2006a, Jones, Porjesz, 2006b, Kamarajan, Porjesz, 2006, Kamarajan, Porjesz, 2004, Kamarajan, Rangaswamy, 2008, Kamarajan, Rangaswamy, 2012, Knyazev, Levin, 2008b, Padmanabhapillai, Porjesz, 2006a, Padmanabhapillai, Tang, 2006b, Rangaswamy, Jones, 2007). Higher spontaneous slow oscillation power and lower slow ERO power that contributes substantially to different chronological peak components of the ERP may appear at first counterintuitive, in light of the evidence that in addition to additive evoked power superimposed on oscillations (Fell, Dietl, 2004), ERP waveforms can be accounted for by the partial phase resetting of EEG oscillations (Fuentemilla et al., 2006, Min et al., 2007). It thus appears reasonable to conclude that if the power in a spontaneous oscillatory frequency is high, there is a relatively higher probability that partial phase resetting of the frequency would render higher power to the phase-locked oscillatory frequency compared to
