computational imaging during video game playing shows dynamic synchronization of cortical and subcortical networks of Emotions
PLOS Biology, 2020Co-Authors: Joana Leitao, Ben Meuleman, Dimitri Van De Ville, Patrik VuilleumierAbstract:Emotions are multifaceted phenomena affecting mind, body, and behavior. 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. 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. According to this framework, Components are recruited in parallel and dynamically synchronized during Emotion episodes. 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. 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. These neural results support theoretical accounts grounding Emotions onto embodied and action-oriented functions triggered by synchronized Component processes.

the temporal dynamics of Emotion antecedent appraisal and the nature of two Component synchronization
2013Co-Authors: Kornelia GentschAbstract:Scherer's Component Process Model proposes a comprehensive architecture of the underlying mechanisms of Emotion elicitation and differentiation. This thesis examined the plausibility of the following predictions: (a) the appraisal process is sequential, (b) appraisal results drive facial expressions, (c) the appraisal and the facial expression Components become synchronized during the response unfolding, and (d) self-beliefs bias the appraisal process. In two experiments, the appraisal of goal conduciveness (motivational valence appraisal), control (general control appraisal), and power (personal ability appraisal) were manipulated in a gambling task. Participants' brain activity (event-related potentials, ERPs) and facial muscle activity (electromyography, EMG, brow and cheek regions) were concurrently recorded. The findings are largely consistent with the predictions: (a) sequential appraisal check effects were repeatedly found in the ERPs. (b) The findings suggest that appraisal results drove facial expressions, which indirectly supports (c) the prediction of Emotion Component synchronization, and (d) biased self-beliefs affected the appraisal process.
