1(a) & 1(b) Correction of Corollary Discharge profile after AcctDCS sessions. The N100 component (–ve peak occurring between 60-150ms) should be attenuated in Talk condition but not in Listen condition indicating adequate corollary discharge. 1(c) Attenuation of correction of Corollary Discharge profile following extended acctDCS sessions. 1(d) & 1(e) rMMN profile correction following AcctDCS sessions. Roving MMN profile should be MMN33>MMN8>MMN3 in decreasing order of negativity as measured by N1 component (–ve peak occurring between 100-200ms). 1(f) Enhancement of rMMN amplitudes (more –ve peaks) and negligible change in rMMN profile (MMN33>MMN8>MMN3 pattern) following extended acctDCS sessions
