With respect to the topographical distribution of evoked power in different frequency bands for both task conditions (please refer to points #8-9 under the subsection 4.1 above), the obtained results are largely in sync with the previous findings, where evoked delta and alpha power have been shown to be posterior phenomena and evoked theta power has been shown to be an anterior phenomenon (Basar-Eroglu and Demiralp, 2001, Brier et al., 2010, Demiralp et al., 1994, Kamarajan, Rangaswamy, 2008, Kamarajan, Rangaswamy, 2012, Klimesch et al., 2005, Pizzagalli et al., 2003, Sauseng et al., 2002, Sauseng et al., 2005). With respect to the topography based on Go/NoGo task conditions, it is evident that NoGo evoked delta and theta power showed relatively higher density more anteriorly compared to the Go condition. However, evoked delta and theta power in the Go condition was higher overall compared to the NoGo condition.
