- The document describes a method called "dynamic parcellation by aggregation of clusters" (dypac) to generate individual brain parcellations from large fMRI datasets. - The method was applied to cneuromod datasets totaling over 30 hours of fMRI data from movies and TV shows. - Results show the individual parcellations have high reproducibility across similar contexts like different seasons of a TV show, and more moderate reproducibility across different stimuli like movies and tasks. Individual parcellations also better predict brain activity than group parcellations.
