Multiple neural mechanisms underlying decision making
Decision making in real lives often involve considerations between many options. However, our knowledge of decision neuroscience is mainly based on experiments that ask people to choose between two items. In this talk, I will discuss how the presence of a third option have dissociable influences on neural signals of the ventromedial prefrontal cortex (vmPFC) and parietal cortex. In addition, in the prefrontal cortex it has been proposed that there is a hierarchical posterior-to-anterior organization that is based on the level of abstractness of mental representations. I will talk about a recent study demonstrating that, depending on the horizon and complexity of choice, vmPFC and frontopolar cortex (FPC) show distinct contributions to decision making.
