Neurocircuits underlying cognition-emotion interaction in a social decision making context

Area of Science:

• Neuroscience
• Cognitive Science
• Social Psychology

Background:

• Decision-making (DM) in social contexts involves complex cognition-emotion interactions.
• Existing research implicates the ventromedial prefrontal cortex (vmPFC), striatum, and amygdala in valuation-based DM, and the hippocampus in context processing.
• The neural mechanisms integrating cognitive and emotional values in social DM remain unclear.

Purpose of the Study:

• To investigate how neural mechanisms integrate cognitive and emotional values in a social decision-making context.
• To identify brain circuits involved in cognitive valuation, emotional valuation, and their integration during social DM.
• To examine the role of social context in modulating these neural processes.

Main Methods:

• A behavioral study (n=73) and a functional magnetic-resonance-imaging (fMRI) study (n=16) were conducted.
• Participants played a card game with a hypothetical opponent, manipulating cognition-emotion interaction.
• Neural activity and functional connectivity were analyzed during social decision-making tasks.

Main Results:

• Behavioral choices were influenced by emotional values from facial stimuli, alongside payoff information.
• The vmPFC, amygdala, and ventral striatum were involved in both cognitive and emotional valuation but played dissociable roles.
• vmPFC and amygdala responses were moderated by social context; vmPFC encoded opponent's gains and acted as a 'final common currency'.
• Functional connectivity between the amygdala, vmPFC, and hippocampus correlated with emotional influence on choices and context processing.

Conclusions:

• The study identified specific brain pathways through which emotions shape subjective values in social decision-making.
• The vmPFC plays a crucial role in integrating cognitive and emotional information, acting as a common valuation currency in social contexts.
• Neural connectivity patterns highlight the interplay between emotion, context, and value-based choices in social interactions.
