Differential representations for affective and informative components of reward in the striatum and hippocampus

The paper investigates how affective and informative reward components are represented in the striatum and hippocampus using high-resolution fMRI and representational similarity analysis, finding differential coding in the dorsal and ventral striatum.

A neural signature of reward

This paper identifies and validates a neural signature of reward using data from 21 studies, showing high accuracy in distinguishing reward from punishment and generalizability across tasks.

Towards a Neurometric-based Construct Validity of Trust

The paper introduces a neurometric approach to assess trust validity using brain patterns, showing high accuracy in predicting trust in a game and validating its relationship with safety beliefs and negative affect.

Variability in the analysis of a single neuroimaging dataset by many teams

The paper shows that different analysis workflows by 70 teams on the same fMRI dataset led to varied results, but meta-analysis found consensus in activated regions.

The influence of relationship closeness on default-mode network connectivity during social interactions

This study investigates how relationship closeness affects default-mode network connectivity during social interactions involving trust.
