- 요약The orbitofrontal cortex (OFC) harbors functional neurons essential for forming a choice circuit, encoding such decision variables as offer value, chosen value, and choice outcome. Accordingly, it has been established as a central hub in value-based decision-making, encoding subjective valuations across different choice paradigms. However, a fundamental question remains: does the OFC maintain a task-invariant, generalized encoding framework, or does it engage task-specific neuronal modules that adapt dynamically based on decision context? This dissertation aims to address this issue by investigating whether OFC neurons exhibit persistent representations across decision tasks or flexibly remap in response to task parameters.Chapter 1 provides an overview of economic decision-making, highlighting the role of the OFC in encoding subjective values across diverse decision contexts. Chapter 2 examines whether distinct OFC neuronal populations encode decision variables for multi-attribute (juice choice, JC) versus single-attribute (single choice, SC) tasks. Results reveal preferential engagement of separate neural populations for each task, supporting functional specialization within the OFC. Chapter 3 investigates whether OFC neurons maintain stable encoding or exhibit flexible remapping across two multi-attribute tasks: juice choice (JC) and delay choice (DC). Findings show a significant overlap of neurons engaged in both tasks, exceeding chance levels. However, no consistent remapping pattern for task-related variables emerges, indicating that OFC neurons adapt dynamically to encode variables within distinct multi-attribute contexts.Chapter 4 evaluates the persistence and adaptability of neural encoding across decision contexts using population decoding and subspace analysis. Results reveal that OFC neurons do not adhere to a fixed remapping scheme but instead engage in flexible adaptation to task demands, favoring a context-sensitive model over rigid modularity.Chapter 5 synthesizes these findings, showing the OFC as a dynamic system that employs dissociable neuronal populations for single- versus multi-attribute choices, while leveraging overlapping, adaptable neurons across different multi-attribute tasks. Overall, this work suggests that the putative OFC choice circuit exhibits the capacity to reconfigure its representation of decision variables under different decision context, offering new insights into the neural basis of value-based decisions.
