Therapeutic doses of ketamine acutely attenuate the aversive effect of losses during decision-making.

This study shows that therapeutic ketamine doses reduce the aversive impact of losses in decision-making in rhesus macaques without affecting gains or other cognitive functions.

Phase of Firing Coding of Learning Variables across Prefrontal Cortex, Anterior Cingulate Cortex and Striatum during Feature Learning

The paper investigates phase-of-firing coding in the prefrontal cortex, anterior cingulate cortex, and striatum during feature learning, finding that phase coding multiplexes information about outcomes, outcome history, and prediction errors.

Cell-type Specific Learning of Attentional Gating in Primate Striatum

The paper identifies cell-type specific changes in cortico-striatal gating during feature-based learning in nonhuman primates.

Double Dissociation of Nicotinic alpha-7 and alpha-4/beta-2 Sub-receptor Agonists for Enhancing Learning and Attentional Filtering of Distraction

The paper investigates the distinct roles of alpha-7 and alpha-4/beta-2 nicotinic acetylcholine receptor agonists in learning and attentional filtering using nonhuman primates, finding a double dissociation in their effects.

Feature Specific Prediction Errors and Surprise across Macaque Fronto-Striatal Circuits during Attention and Learning

The paper shows neurons in fronto-striatal circuits encode feature-specific prediction errors during attention and learning, contributing to feature-based attention updates.
