Studies based on a paradigm of free or natural viewing have revealed characteristics that allow us to know how the brain quest fryer processes stimuli within a natural environment.This method has been little used to study brain function.With a connectivity approach, we examine the processing of emotions using an exploratory method to analyze functional magnetic resonance imaging (fMRI) data.This research describes our approach to modeling stress paradigms suitable for neuroimaging environments.

We showed a short film (4.54 minutes) with high negative emotional valence and high arousal content to 24 healthy male subjects (36.42 years old; SD 30x24x24 wall cabinet = 12.14) during fMRI.

Independent component analysis (ICA) was used to identify networks based on spatial statistical independence.Through this analysis we identified the sensorimotor system and its influence on the dorsal attention and default-mode networks, which in turn have reciprocal activity and modulate networks described as emotional.
