| summary | Functional magnetic resonance imaging (fMRI), which allows non-invasive measurement of brain hemodynamic activity, has significantly increased possibilities to study the neural basis of human perceptual, cognitive, and emotional functions. Pioneering studies published in 2004 by Bartels et al. and Hasson et al. paved way for the use of highly naturalistic stimuli such as feature films in fMRI studies. While these early studies focused on sensory-cortical processing of visual perception, we showed in 2008 that prefrontal cortical and subcortical (e.g., amygdala) areas involved in emotions and social cognition also exhibit significant inter-subject correlation of brain activity when watching a contextually primed and emotionally engaging movie clip. In our subsequent studies, we have utilized movie clips as naturalistic stimuli to probe the cerebral mechanisms underlying emotions, social cognition and -perception. Results from these studies will be presented in this talk. We have also tested and developed new data analysis methods, including ones that allow estimation of instantaneous (i.e., single-TR) synchrony of hemodynamic activity between subjects and brain areas to study dynamic network activity of the human brain when subjects are watching movies. These freely available data analysis methods will also be briefly introduced in this talk. Most recently, we have explored the use of movies as naturalistic stimuli in combined MEG/EEG studies, which brings the benefits of directly measuring neural activity and superior temporal resolution, but is complicated by the ill-posed nature of the electromagnetic inverse problem. |
