Integration of Reward-Based and Context-Based Decision Making in Human Prefrontal Cortex

Abstract

Event Abstract Back to Event Integration of Reward-Based and Context-Based Decision Making in Human Prefrontal Cortex S. Duverne1* and E. Koechlin1 1 INSERM, Ecole normale superieure , Canada The lateral prefrontal cortex (PFC) implements task selection based on contextual information, whereas medial PFC is involved in selection based on reward information. Little is known, however, on how reward-based and context-based selection processes are integrated together. Using functional magnetic resonance imaging, we recorded brain activity in twenty-three participants responding to letter stimuli by choosing between two tasks based on either contextual cues or variable reward history associated with each task. We found that the lateral PFC regions were involved in both reward-based and context-based task selection. Reward-based trials, however, involved additional medial PFC regions, while lateral PFC activations increased in reward-compared to context-based trials. The results suggest that medial PFC regions contribute to decision-making by biasing selection processes in the lateral PFC according to rewarding values of task-sets, while lateral PFC integrates contextual and motivational signals to achieve task-set selection underlying executive control of behavior.
