This study compares the retrograde transduction efficiency of four viral vectors in dopaminergic neurons of rhesus monkeys after striatal injection.

The paper introduces MAGIC MRI, a gene-based reporter system for non-invasive neural tracing in vivo, validated in rodents and rhesus macaques.

This study shows that visual category learning enhances category separability in monkey inferior temporal cortex by increasing category-selective neurons and prolonging their responses.

This study identifies distinct OFC-subcortical pathways in macaques that support experience-based and inference-based value updating during adaptive decision-making.

The paper shows that energy landscapes in prefrontal cortex neural activity predict decision consistency, reflecting decision confidence in macaques.

The paper characterizes two ultrapotent chemogenetic ligands in rhesus macaques, showing good brain penetrance and safety for potential neuroscience research applications.

This study disrupts the connection between the orbitofrontal cortex and rostromedial caudate nucleus in macaques using chemogenetics, showing it impairs reward-based motivational control of goal-directed actions.

The paper shows that neurons in the primate caudate head encode temporally discounted value for delayed rewards, essential for motivation.

The paper introduces a convolutional neural network to estimate synaptic connectivity from spike trains without requiring parameter tuning, and applies it to construct neuronal circuit diagrams in monkey cortical areas.

This study shows that macaques can categorize animate and inanimate objects using curvilinear image features without training.

This paper develops a method to reconstruct neuronal circuitry from spike trains using a generalized linear model, validated on rat hippocampal data.

The paper develops new DREADD agonists and a PET radiotracer for improved neuronal activity manipulation and noninvasive projection mapping in neurotheranostics.

This study examines the roles of the lateral prefrontal cortex and orbitofrontal cortex in abstract rule learning and reversal in monkeys, finding distinct impairments in each region.
