Targeted stimulation of an orbitofrontal network disrupts decisions based on inferred, not experienced outcomes

This study shows that stimulating the orbitofrontal cortex impairs decision-making based on inferred outcomes but not on direct experience.

Targeted stimulation of human orbitofrontal networks disrupts outcome-guided behavior

This study uses cTBS to disrupt human OFC network activity and shows impaired outcome-guided behavior after reward devaluation.

Dopamine neuron ensembles signal the content of sensory prediction errors

The paper shows that groups of dopamine neurons in rats and human midbrain signal specific sensory prediction errors through ensemble firing patterns.
