This study compares persistence in decision-making across mice, monkeys, and humans in a dynamic task, finding that primates outlast mice in exploitation strategies.

This paper evaluates effective connectivity metrics for reconstructing neural network topology under data limitations, finding that multivariate transfer entropy is most accurate but slow, while partial cross-correlation is efficient for larger networks.

This paper introduces a foraging-theory-based model that better captures human behavioral diversity in sequential decision-making compared to traditional value-comparison models.

The paper shows that human exploration behavior follows a U-shaped pattern with the ratio of volatility to stochasticity in uncertain environments, with optimal performance at intermediate uncertainty ratios.

The paper identifies a dominant nonlinear axis of individual variability in decision-making tasks, showing that exploration tendency, rather than personality or learning parameters, drives differences in performance.

This study identifies distinct computational mechanisms of uncertainty processing in anxiety and apathy, showing how they influence exploratory behaviors through different perceptions of volatility and stochasticity.

This study shows humans use compare-to-threshold computations in decision-making tasks, outperforming traditional reinforcement learning models.

This paper introduces a flexible multi-step hypothesis testing method using cluster-based permutation tests with LMEs and GLMEs to analyze human ECoG data, improving statistical power and accounting for random effects.

The paper identifies a low-dimensional behavioral manifold that captures exploration-exploitation decision-making and links it to symptoms of apathy and anxiety.

The paper shows that pre-trial firing rate patterns in human dlPFC predict conflict resolution in cognitive tasks, with distinct but related patterns for different conflict types.

The paper quantitatively distinguishes sleep functions in development, showing an abrupt transition from neural reorganization to repair between 2-3 years in humans.
