Monoaminergic variation, cortical structure, and disaster trauma interact to shape emotional vulnerability

The paper examines how monoaminergic genetic variation, cortical structure, and trauma interact to influence emotional vulnerability using a large cohort dataset.

Recurrent neural network dynamics may not purely reflect cognitive strategies: A commentary on Ji-An et al. (Nature, 2025)

The paper critiques Ji-An et al.'s use of RNNs to model cognitive strategies, suggesting RNN dynamics may capture non-cognitive processes rather than purely reflect cognitive strategies.

The preference for surprise in reinforcement learning underlies the differences in developmental changes in risk preference between autistic and neurotypical youth

Cardiac cycle affects the asymmetric value updating in instrumental reward learning

This study shows that cardiac cycle phase influences asymmetric value updating in instrumental reward learning, with higher learning rates for positive prediction errors during systole.

Computational Psychiatry Research Map (CPSYMAP): a New Database for Visualizing Research Papers

The paper introduces CPSYMAP, a database that visualizes computational psychiatry research papers in a 2D map to show distribution across neuroscience, psychiatry, and computational dimensions.

Exploration-related strategy mediates negative coupling between decision-making performance and psychiatric symptoms

The paper identifies a psychiatric symptom dimension linked to decision-making performance through exploration strategies in a healthy population.
