What are the essential neural circuits coordinating the complex, multiple, and often abrupt changes in both mental and bodily states that are characteristically associated with emotion? Do they rely on specialized modules or distributed systems in the brain, and which are these? Such questions have been hotly debated in past decades. However, the functional and neuroanatomical organization of emotion is still unresolved.

These neural results support theoretical accounts grounding emotions onto embodied and action-oriented functions triggered by synchronized component processes.Ĭitation: Leitão J, Meuleman B, Van De Ville D, Vuilleumier P (2020) Computational imaging during video game playing shows dynamic synchronization of cortical and subcortical networks of emotions. We show that each emotion component recruits large-scale cortico-subcortical networks, and that moments of dynamic synchronization between components selectively engage basal ganglia, sensory-motor structures, and midline brain areas.
Here, we use functional MRI (fMRI) to investigate brain-wide systems engaged by theoretically defined components and measure their synchronization during an interactive emotion-eliciting video game.
According to this framework, components are recruited in parallel and dynamically synchronized during emotion episodes. In contrast, distributed patterns accord with multi-componential theories whereby emotions emerge from appraisal processes triggered by current events, combined with motivational, expressive, and physiological mechanisms orchestrating behavioral responses. Previous studies sought to link particular emotion categories (e.g., fear) or dimensions (e.g., valence) to specific brain substrates but generally found distributed and overlapping activation patterns across various emotions. Emotions are multifaceted phenomena affecting mind, body, and behavior.
