This paper introduces a deformation in probability estimation to a reinforcement learning model, linking it to anxious-depression symptoms in psychiatric disorders.

This study examines the impact of a 15-day synbiotic intervention on cognitive functions in healthy young women, finding selective improvements in visual attention but not in working memory or inhibitory control.

The paper evaluates a modular neural recording platform built from commercial components, showing it can recover LFP-like waveforms and detect spikes, though with signal quality issues.

The paper introduces a method to create controllable 3D point-light displays using a game engine for biological motion research, showing it replicates known perceptual biases.

The paper investigates SF coding in the IT cortex of macaque monkeys and finds that SF representation is distinct from category coding, with SF profiles predicting category selectivity at the population level.

A single session of fast-paced video gaming improves working-memory precision and increases prefrontal alpha oscillations.

This study investigates how emotional content affects working memory precision, finding a negativity bias and altered perception of emotional valence.

This study examines conscious and unconscious emotional processing through behavioral and pupillary responses, finding distinct patterns in accuracy, pupil size, and task parameters between states.

This study compares two reinforcement learning models in volatile environments, finding that separate reward and punishment learning rates improve performance, with higher reward learning rates being more beneficial.

The paper shows that higher meta-cognitive ability is linked to reduced reliance on overconfident model-free learning in variable environments.

The paper proposes a k-nearest neighbor method to improve parameter estimation in reinforcement learning models, showing better reliability than maximum likelihood approaches.

The paper shows that prefrontal neurons enhance spatial representation during cognitive tasks by altering population-level activity rather than individual neuron selectivity.
