Decisions are central to life. Every aspect no matter how small requires a decision, often with complex consequences. My long term interest is to understand and study the process of decision making: first by understanding the neural correlates and second by integrating the neural correlates of decision-making with theories in economics and learning psychology. To this end, I am interested in pursuing the neural correlates of decision-making in the frontal cortex, more specifically how are decisions made when taking the future into context and how do these events correlate with the ideas initially presented in the psychology of learning and behavior?
Past research demonstrated profound deficits in decision making following damage to the orbitofrontal cortex (OFC). These studies implicated the OFC in decision making. However, prior research has not investigated the role of the OFC in decision making in the absence of explicit instructional cues. As a result, it is not know how the OFC represents decisions when required to internally generate a response or decide upon a course of action. Other learning systems, such as the hippocampus and ventral striatum have demonstrated reward related activity when a rat was at a physically different location on a maze. During the formation of a choice the rat represents the consequences of his decisions. These representations can be seen in the non-local neural representations from hippocampus which display the rat representing his forward paths, ahead of his actual position.
