Unrestricted temporal PCA solution. Top: Time courses of Varimax-rotated covariance loadings for the first five CSD factors extracted (89.3% total variance explained). Labels indicate the peak latency of the factor loadings relative to stimulus onset. Bottom: Corresponding factor score topographies (nose at top) for both tasks and groups (pooled across old and new items) with percentage of explained variance. Factors 161, 220 and 442 clearly corresponded to lateral inferior-parietal N1 sinks (left-lateralized for words), task-specific occipital P2 sources, and parietal P3 sources, respectively. Factor 723 had a more complex topography, with a centroparietal (CP) source maximum accompanied by a mid-frontal and a right inferior occipitoparietal sink.
