Value coding by primate amygdala neurons complies with economic choice theory

This study shows primate amygdala neurons encode subjective values consistent with economic choice theory, integrating reward probability and magnitude into decision-making.

Coding of the basic components of subjective value in primate dopamine neurons: subjectively weighted reward amount and probability

The paper shows that dopamine neurons in monkeys encode subjective reward value by integrating utility and subjectively weighted probability, aligning with observed choice behavior.

Social risk coding by amygdala activity and connectivity with dorsal anterior cingulate cortex

The paper examines how social risk affects neural activity in the amygdala and its connection to the dorsal anterior cingulate cortex in human volunteers.

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.

Worth the work? Monkeys discount rewards by a subjective adapting effort cost

This paper shows monkeys adjust their reward-effort decisions based on subjective effort costs influenced by prior experience, using a subtractive model of effort disutility.

Mechanisms of adjustments to different types of uncertainty in the reward environment across mice and monkeys

This study investigates how mice and monkeys adjust to different types of uncertainty in reward environments using choice data and reinforcement learning models.

Systematic comparison of risky choices in humans and monkeys

This study compares risky choices between humans and monkeys, finding comparable decision-making patterns despite differences in subjective values.

Formal cooperation in macaque monkeys obtained via single-payoff change from formal coordination games

This study shows macaque monkeys can cooperate in iterated Prisoner's Dilemma games after being exposed to coordination games, with cooperation decreasing as temptation payoffs increase.

Reliable population signal of subjective economic value from unreliable neurons in primate orbitofrontal cortex

The paper shows that unreliable individual neurons in monkey orbitofrontal cortex collectively encode reliable economic value signals during choice tasks.

Mechanisms Underlying Economic Revealed Preference Of Multi-Component Bundles In Primate Orbitofrontal Cortex

The paper applies random utility modelling to study decision-making in non-human primates, showing how neuronal activity in the orbitofrontal cortex reflects utility and choice preferences in multi-component bundles.

Single-dimensional human brain signals for two-dimensional economic choice options

The paper demonstrates that neural signals in reward-related brain regions follow choice indifference curves, indicating integration of multiple reward components into scalar signals.

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.
