The Neurobiology of Cognitive Fatigue and Its Influence on Effort-Based Choice

This study investigates how cognitive fatigue affects effort-based decision-making using fMRI, finding that fatigued individuals are more likely to choose lower reward options requiring less effort.

Control of tongue movements by the Purkinje cells of the cerebellum

This study investigates how Purkinje cells in the cerebellum control tongue movements in marmosets by suppressing their activity during specific phases of movement.

Effort cost of harvest affects decisions and movement vigor of marmosets during foraging

The paper shows that increased effort cost of harvest in marmosets leads to longer work duration, reduced movement vigor, and pupil constriction, suggesting a coordinated neural response to optimize fitness.
