Dopamine neurons encode trial-by-trial subjective reward value in an auction-like task

This study shows that dopamine neurons in rhesus monkeys encode trial-by-trial subjective reward value through BDM auction-like bidding behavior.

Reward-specific satiety affects subjective value signals in orbitofrontal cortex during multi-component economic choice

This study shows that reward-specific satiety reduces subjective reward value signals in orbitofrontal cortex during multi-component economic choices.

Experimentally revealed stochastic preferences for multi-component choice options

The paper investigates how humans and monkeys make choices between multi-component rewards, showing that preferences can be represented as single-dimensional trade-offs using indifference curves and validated by machine learning.
