Neural network dynamics associated with facial and subjective emotional responses.

ABSTRACT: Emotions comprise multiple coordinated responses, including facial expressions and subjective experiences. Although functional magnetic resonance imaging (fMRI) studies have identified brain regions associated with facial or emotional responses, few have simultaneously assessed and statistically dissociated components. Additionally, the functional networks associated with these emotional responses and the dynamic interplay between such networks remain uncertain. To investigate these issues, we measured fMRI while participants viewed emotional films, as well as their facial videos and dynamic valence ratings. Regional activity analysis revealed that facial responses (lip-corner-pulling actions) were associated with activation in the limbic regions and somatosensory motor cortices. Subjectiv
