Abstract :
Emotional processing has an important role in social interaction. We report the findings about the Independent Component
Analysis carried out on a fMRI set obtained with a paradigm of face emotional processing. The results showed that an independent
component, mainly cerebellar-medial-frontal, had a positive modulation associated with fear processing. Also, another independent
component, mainly parahippocampal-prefrontal, showed a negative modulation that could be associated with implicit reappraisal
of emotional stimuli. Independent Component Analysis could serve as a method to understand complex cognitive processes and
their underlying neural dynamics.
