The paper shows that biased neural replay of aversive and uncertain outcomes underlies irrational decision making in humans.

Risk preferences causally rely on parietal magnitude representations: Evidence from combined TMS-fMRI

This study shows that parietal magnitude representations causally influence risk preferences by increasing noise in small-magnitude encoding, leading to more risk-seeking behavior.

Multifaceted confidence in exploratory choice

The paper investigates confidence in exploratory choices and finds no difference in confidence between immediate and total reward in a bandit task, contradicting predictions.

This study shows that humans, rats, and mice invest time based on statistical confidence, approaching optimal time allocation strategies under uncertainty.

Mice-side bias: Deliberative decision making in a model of rule revision reveals 'myside' confirmation bias-like cognitive processes in mice.

This paper demonstrates myside confirmation bias-like behavior in mice during rule revision tasks, showing it emerges through deliberative processes rather than heuristic responses.

The paper shows that subjective values change during decision-making tasks and introduces a model to detect these changes in choices and neural signals.

Synaptic plasticity in the orbitofrontal cortex explains how risk attitude adapts to the range of risk prospects

The paper shows that risk attitudes adapt to the range of risk prospects through hebbian plasticity in the orbitofrontal cortex, leading to context-dependent, irrational behavior.
