Abstract Humans form complex societies in which we routinely engage in social decision-making regarding the allocation of resources among ourselves and others. One dimension that characterizes social decision-making in particular is whether to priori

Abstract Trust attitude is a social personality trait linked with the estimation of others’ trustworthiness. Trusting others, however, can have substantial negative effects on mental health, such as the development of depression. Despite significan

In order to validate a previously inferred function of the lateral prefrontal cortex (LPFC)-caudate nucleus (CdN) pathway in humans in inhibitory control and working memory, Oguchi et al used pathway-selective chemogenetic manipulation of neural acti

Macaque monkeys are prime animal models for studying the neural mechanisms of decision-making because of their close kinship with humans. Manipulation of neural activity during decision-making tasks is essential for approaching the causal relationshi

Behavioral responses to unfair distribution have been measured mainly using the Ultimatum Game (UG). Recent studies examining the biological basis of behavioral responses to unfair distribution have focused attention on the role of the serotonin tran

Rewards that require high effort tend to be preferred over those that require low effort. Here, the authors show how the effort of obtaining rewards affects reward-related activity of dopamine neurons, and in turn the speed of learning stimulus-rewar

Oxytocin (OXT) is known to play an important role in trust, whereas the involvement of other peptide hormones has not been evaluated. In this study, we focused on microsatellite polymorphisms in the intron of the arginine-vasopressin receptor 1a (AVP

Midbrain dopamine neurons encode reward prediction error (RPE) signals and are involved in reinforcement learning, which in turn influences various decision-making behaviors. Recently, it was revealed that dopamine neurons incorporate non-reward info
