For the time domain, tPCA factor scores corresponding to CSD components previously identified for this novelty oddball paradigm (Tenke et al., 2010) were submitted to repeated measures ANOVAs with group (patients, controls) and gender (male, female) as between-subjects factors, and condition (target, novel) as a within-subjects factor (for the sake of simplicity and to increase statistical power, nontarget stimuli were not included in these analyses). The selection of recording sites for comparing experimental effects in these ANOVAs was guided by our previous findings using a 67-channel EEG montage (Tenke et al., 2010), and consisted of either midline sites or lateral, homologous recording sites over both hemispheres, and thereby adding either site, or site and hemisphere as within-subjects factors to the design. However, because recording sites were selected on the premise that they collectively represent sink or source activity associated with a given CSD component, site effects were not further pursued in these analyses. For the time-frequency domain, tfPCA factor scores corresponding to CSD-ERSP components unambiguously related to alpha ERS or alpha ERD were submitted to similar repeated measures ANOVAs, selecting
