Topographies and reconstructed ERPs for the first six factors from the adult PCA. Each row represents a factor in the rotated solution. The left-most column depicts the contribution of the factor to the grand-average ERP (transparent lines) at the maximum electrode (marked by white dot). The other columns present the factors’ topographies separately for all conditions. Please note that the extrapolated topography becomes unreliable outside the area covered by electrodes and tends towards extreme values due to the simplistic biharmonic interpolation. This plot is created in the script 03b_topoplot_allFactors.R.
