We investigate “real-life cognition” in the brain by using naturalistic stimulation, such as watching motion pictures in an MRI scanner. We combine MR data acquisition with other data modalities like simultaneous high-speed eye tracking (A) to investigate which aspects of the rich stimulus are processed synchronously across individuals. (B) Shows brain response similarities for people that watch the two-hour movie “Forrest Gump” in the scanner, compared to another recording where the same individuals listened to an audio-only version of “Forrest Gump” for the blind. (C) shows inter-individual differences of the focus of visual attention for an excerpt of the movie, and how the cuts in an edited movie synchronize this focus for a brief period.
