Identity-specific reward expectations in orbitofrontal cortex guide goal-directed choices

How reward identity representations influence choice remains unclear in neuroeconomic decision-making models. This fMRI study shows that identity-specific expectations in the human lateral orbitofront...

Neural mechanisms of credit assignment for delayed outcomes during contingent learning

Orbitofrontal cortex and hippocampus reinstate representations of causal choices to associate with delayed outcomes, and the frontal pole supports this credit assignment process by maintaining pending...
