Decision making in an embodied system: Effector-specific and effector-independent neural computations underlying value-based decision making
Decision making generally translates to action selection because every organism is an embodied system that must decide how to interact with the physical world. Neural comparison processes operate at multiple levels of representation insofar as different neural networks represent options under consideration and actions for obtaining them at different levels. How does the nervous system compute decision values at different levels of representation and integrate them? This research has begun to shed light on effector-specific and effector-independent neural computations underlying value-based decision making with the aim of achieving a complete mechanistic understanding of how people make and implement decisions.
