LL and SL neural pattern similarities. Full intersubject similarity matrixes (upper) where each row shows the neural pattern similarities in each brain region at varying lags across columns. Brain regions are ordered by their peak lags. Intersubject pattern similarities for each TR were averaged across all TRs in the story. Lags with the peak correlation values are color-coded. Significant peak lags are marked with wide (horizontal) colored bars (P < .05, FDR correction). Nonsignificant peak lags are marked with narrow colored bars. The correlation values are normalized with Fisher’s transformation and then z-scored across lags. Region of interest (ROI)s with significant peak lags are plotted on the brain (lower). LL similarities peak at lag 0 in most brain regions, reflecting that the listeners are synchronized. On the other hand, SL similarities often peak at negative lags, indicating that the speaker precedes the listeners.
