The superior colliculus arbitrates whole-brain dynamics for unconscious visual insight

The paper identifies the superior colliculus as a key structure in whole-brain dynamics during sudden visual insight using fMRI data from an insight task.

Overcoming pride via the dorsal ACC underlies acceptance of unfair offers

This study uses fMRI and the drift diffusion model to show that dorsal ACC activity mediates the suppression of inequity aversion, enabling acceptance of unfair offers in the ultimatum game.

Forget and Forgive: A Neurocognitive Mechanism for Increased Cooperation During Group Formation

The paper investigates how group size affects cooperation using a dynamic prisoners dilemma experiment with fMRI, finding that increased cooperation in larger groups results from interactions between prosocial tendencies and memory confidence.

Selfish behavior requires top-down control of prosocial motivation

The paper investigates the neural mechanisms underlying proself behaviors by analyzing fMRI data from an ultimatum game, revealing the role of top-down control of prosocial motives in proself decisions.

Value computations underlying human proposer behaviour in the Ultimatum Game

This study models human proposer behavior in the Ultimatum Game, finding that risk perception is common across decisions, while nonlinear weighting of acceptance probabilities is unique to social interactions involving inferred opponent valuations.
