Methodological advances and their resulting observations shape the gain of knowledge on the human brain and behavior. The functional architecture of the brain has been studied extensively using task-based and resting-state fMRI studies, which grant insight into the network organization of the brain. However, these techniques for studying the brain possess limited ecological validity, which may restrict their generalizability.
Recent years have seen rising interest in naturalistic stimuli – such as movies or auditory narratives – to increase the ecological validity of laboratory research. Naturalistic stimuli are complex, dynamic and continuous, which more strongly imitates daily life experiences and allows the study of the brain in a more natural environment.
This symposium will introduce naturalistic stimuli and their advantages compared to more established paradigms (Christian Häusler). We will compare test-retest reliability of movie-fMRI and resting-state fMRI (Dr. Xing Qian). Furthermore, we will explore the usability of movie fMRI for the study of inter-individual differences in functional networks (Jean-Phillipe Kröll) and the general functional topography (Dr. Xuan Li). Lastly, we will present the usage of auditory narratives to map the individual language network (Dr. Martin Wegrzyn). We will end with a plenum-discussion on the interpretation and potential future of this exciting new field.
