Follow-up analyses revealed reduced EROTOT power in LTAAs vs. NACs for the:- (i) δ1 at Pz, (accounting for 7.9% of the variance), (ii) θ1 at Pz and CPz (accounting for 7.6% and 4.8% of the variance), and (iii) θ2 at Cz, CPz, Pz and FCz (accounting for 9.5%, 9.2%, 8.0% and 5.7% of the variance). Discriminant analysis confirmed the independent contribution of these measures at all electrode sites noted.
