Statistical analysis methods for quantifying brain activity during naturalistic paradigms Enrico Glerean PhD D.Sc Staff Scientist at Aalto School of Science Aalto University
The use of naturalistic stimuli during brain data collection (e.g. watching a feature film, listening to an audio book, listening to music) has proved to be a very powerful tool in studying brain activity under life-like conditions. However, the added uncontrolled complexity of naturalistic stimuli has brought new challenges to develop methods to understand brain data measured with naturalistic paradigms. In this talk I will intuitively introduce methods such as Intersubject Correlation, Intersubject Phase Synchronisation, Intersubject Functional Connectivity and Intersubejct-Representation Similarity Analysis. These methods have proved to be very useful in understanding the similarities and differences of individual brains processing complex naturalistic stimuli in healthy and clinical populations.
