Theta-filtered response-locked event-related potential (ERP) and time-frequency Principal Component Analysis (TF-PCA) for False Alarms plotted at FCz: (A) Theta-filtered grand average ERP waveform plotted at FCz. (B) The average time-frequency surface used in the principal component analysis. (C) Principal components extracted accounting for 69.73% of the variance. (D) Topographical depiction of the mean spatial distribution for each principal component. (E) Scree plot of singular values which was used to determine a four-component solution.
