Naturalistic Stimuli in Affective Neuroimaging: A Review

Heini Saarimäki
2021 Frontiers in Human Neuroscience  
Naturalistic stimuli such as movies, music, and spoken and written stories elicit strong emotions and allow brain imaging of emotions in close-to-real-life conditions.  ...  Emotions are multi-component phenomena: relevant stimuli lead to automatic changes in multiple functional components including perception, physiology, behavior, and conscious experiences.  ...  In BOLD-fMRI studies, functional connectivity is defined as stimulusdependent co-activation of different brain regions, usually measured as a correlation between two regions' time series.  ...
