Figure 5.

analyzes 2D Euclidean embeddings of instantaneous brain states segmented in terms of both block-design task contrasts, and by the acquisition time of temporally aligned task blocks during the SOCIAL scan. The bar chart shows the mean value of the bootstrapped structural similarity index of the within (blue=mentalizing, and yellow=random) and the between (green) block-design-contrast embeddings. For each task contrast, the sample distribution was bootstrapped from 25 realizations of 250 timepoints, randomly sampled from the group-level data set. Fewer bootstrap time points are used to accommodate the reduced sample size in each segmentation. Daggers above the bar chart point to the aligned block times whose embedding density images are displayed in the inset images. Red boxes define the boundary regions given closer scrutiny in figure 6.
