This study uses fMRI to show that a two-dimensional subjective value space is represented in the cognitive mapping system during risky decision-making.

This study explores how cognitive control affects the geometry of cognitive maps in the brain and in neural networks, showing stable and context-dependent representations that relate to task demands.

This study investigates how the brain assigns credit for inferred relationships in structured environments using a novel task and Bayesian model, finding that the medial prefrontal cortex represents hierarchical associations and tracks abstract task positions.

The paper shows humans use grid-like neural codes in the brain to infer solutions in abstract social hierarchies, linking cognitive maps to decision-making.

This study examines how the human hippocampus encodes contextual and goal information during goal-directed navigation, showing context-specific future goal representations and anticipatory activity patterns.

The paper investigates how the brain represents and combines abstract social hierarchies using neural activity patterns in specific brain regions.

The paper shows humans use Bayesian inference to model group dynamics in decision-making, outperforming existing models in explaining behavior in the Volunteers Dilemma.
