The lateral prefrontal cortex and moral goal pursuit

Area of Science:

• Neuroscience
• Social Neuroscience
• Cognitive Neuroscience

Background:

• Humans exhibit prosocial behaviors like fairness and honesty, even when conflicting with self-interest.
• The lateral prefrontal cortex (LPFC) is implicated in pursuing these moral goals.
• The specific computational function of the LPFC in moral decision-making remains incompletely understood.

Purpose of the Study:

• To integrate insights from hierarchical control and value-based choice theories.
• To elucidate the computational role of the LPFC in supporting the pursuit of moral goals.
• To provide a framework for future research on the neural basis of morality.

Main Methods:

• This study offers a theoretical integration of existing research.
• It synthesizes findings from hierarchical control and value-based choice literature.
• No new empirical data were collected; it is a conceptual review.

Main Results:

• The LPFC's role in moral goal pursuit can be understood through its function in implementing abstract goals and evaluating action values.
• Hierarchical control explains how the LPFC maintains and enacts high-level moral principles.
• Value-based choice mechanisms highlight how the LPFC weighs the subjective value of moral actions.

Conclusions:

• The lateral prefrontal cortex plays a crucial role in enabling individuals to act according to moral principles.
• An integrative approach combining hierarchical control and value-based choice offers a more comprehensive understanding of LPFC function in morality.
• Future research should investigate the dynamic neural coding underlying these processes to further unravel the neuroscience of morality.
