The Brain Vision Analyzer package (BVA, Brain Products, Munich, Germany), was utilized for pre-processing of the data, computation of ERP waveforms and extraction of the peak amplitudes of the ERP components. The open-source, MATLAB-based EEGLAB Toolbox (Delorme and Makeig, 2004) was used for computation of event-related TFRs and extraction of ERO power measures from these TFRs, with additional functionality added to the toolbox as required. The methodology used for the analysis of the event-related EEG data, as described below, was similar to the methodology used in Jones et al. (2006) and Rangaswamy et al. (2007), with important differences indicated..
