The interaction between repetition and event overlap. A. MTL regions showing a significant interaction between repetition-related activation changes and condition. B. Follow-up ROI analyses illustrating repetition-related activation changes within MTL subregions separately for non-overlapping (gray bars) and overlapping (white bars) events. Bar heights represent group means; error bars represent standard error. Positive values reflect repetition enhancement (last > first), while negative values represent repetition suppression (first > last). Asterisks above or below bars indicate significant repetition-related activation changes for each condition at p < 0.05. Bars with tensor symbols designate a significant interaction between repetition-related activation changes and condition at p < 0.05 (as would be expected based on the contrast). A = Anterior, P = Posterior. C. CA₁ and DG/CA_2,3 responses to repetition of overlapping and non-overlapping events. Tensor symbol indicates main effect of region. D. Midbrain region showing a significant repetition × condition interaction. E. Follow-up ROI analyses illustrating repetition-related activation changes within midbrain separately for non-overlapping and overlapping events.
